Bioengineers develop a new strategy for accurate prediction of cellular metabolic fluxes
A team of pioneering South Korean scientists has developed a new strategy for accurately predicting cellular metabolic fluxes under various genotypic and environmental conditions. This groundbreaking research is published in the journal Proceedings of the National Academy of Sciences of the USA (PNAS) on August 2, 2010. To understand cellular metabolism and predict its metabolic capability at systems-level, systems biological analysis by modeling and simulation of metabolic network plays an important role. The team from the Korea Advanced Institute of Science and Technology (KAIST), led by Distinguished Professor Sang Yup Lee, focused their research on the development of a new strategy for more accurate prediction of cellular metabolism. “For strain improvement, biologists have made every effort to understand the global picture of biological systems and investigate the changes of all metabolic fluxes of the system under changing genotypic and environmental conditions,” said Lee. The accumulation of omics data, including genome, transcriptome, proteome, metabolome, and fluxome, provides an opportunity to understand the cellular physiology and metabolic characteristics at systems-level. With the availability of the fully annotated genome sequence, the genome-scale in silico (means “performed on computer or via computer simulation.”) metabolic models for a number of organisms have been successfully developed to improve our understanding on these biological systems. With these advances, the development of new simulation methods to analyze and integrate systematically large amounts of biological data and predict cellular metabolic capability for systems biological analysis is important. Information used to reconstruct the genome-scale in silico cell is not yet complete, which can make the simulation results different from the physiological performances of the real cell. Thus, additional information and procedures, such as providing additional constraints (constraint: a term to exclude incorrect metabolic fluxes by restricting the solution space of in silico cell) to the model, are often incorporated to improve the accuracy of the in silico cell. By employing information generated from the genome sequence and annotation, the KAIST team developed a new set of constraints, called Grouping Reaction (GR) constraints, to accurately predict metabolic fluxes. Based on the genomic information, functionally related reactions were organized into different groups. These groups were considered for the generation of GR constraints, as condition- and objective function- independent constraints. Since the method developed in this study does not require complex information but only the genome sequence and annotation, this strategy can be applied to any organism with a completely annotated genome sequence. “As we become increasingly concerned with environmental problems and the limits of fossil resources, bio-based production of chemicals from renewable biomass has been receiving great attention. Systems biological analysis by modeling and simulation of biological systems, to understand cellular metabolism and identify the targets for the strain improvement, has provided a new paradigm for developing successful bioprocesses,” concluded Lee. This new strategy for predicting cellular metabolism is expected to contribute to more accurate determination of cellular metabolic characteristics, and consequently to the development of metabolic engineering strategies for the efficient production of important industrial products and identification of new drug targets in pathogens.”

Native-like Spider Silk Produced in Metabolically Engineered Bacterium
Microscopic picture of 285 kilodalton recombinant spider silk fiber Researchers have long envied spiders’ ability to manufacture silk that is light-weighted while as strong and tough as steel or Kevlar. Indeed, finer than human hair, five times stronger by weight than steel, and three times tougher than the top quality man-made fiber Kevlar, spider dragline silk is an ideal material for numerous applications. Suggested industrial applications have ranged from parachute cords and protective clothing to composite materials in aircrafts. Also, many biomedical applications are envisioned due to its biocompatibility and biodegradability. Unfortunately, natural dragline silk cannot be conveniently obtained by farming spiders because they are highly territorial and aggressive. To develop a more sustainable process, can scientists mass-produce artificial silk while maintaining the amazing properties of native silk? That is something Sang Yup Lee at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, the Republic of Korea, and his collaborators, Professor Young Hwan Park at Seoul National University and Professor David Kaplan at Tufts University, wanted to figure out. Their method is very similar to what spiders essentially do: first, expression of recombinant silk proteins; second, making the soluble silk proteins into water-insoluble fibers through spinning. For the successful expression of high molecular weight spider silk protein, Professor Lee and his colleagues pieced together the silk gene from chemically synthesized oligonucleotides, and then inserted it into the expression host (in this case, an industrially safe bacterium Escherichia coli which is normally found in our gut). Initially, the bacterium refused to the challenging task of producing high molecular weight spider silk protein due to the unique characteristics of the protein, such as extremely large size, repetitive nature of the protein structure, and biased abundance of a particular amino acid glycine. “To make E. coli synthesize this ultra high molecular weight (as big as 285 kilodalton) spider silk protein having highly repetitive amino acid sequence, we helped E. coli overcome the difficulties by systems metabolic engineering,” says Sang Yup Lee, Distinguished Professor of KAIST, who led this project. His team boosted the pool of glycyl-tRNA, the major building block of spider silk protein synthesis. “We could obtain appreciable expression of the 285 kilodalton spider silk protein, which is the largest recombinant silk protein ever produced in E. coli. That was really incredible.” says Dr. Xia. But this was only step one. The KAIST team performed high-cell-density cultures for mass production of the recombinant spider silk protein. Then, the team developed a simple, easy to scale-up purification process for the recombinant spider silk protein. The purified spider silk protein could be spun into beautiful silk fiber. To study the mechanical properties of the artificial spider silk, the researchers determined tenacity, elongation, and Young’s modulus, the three critical mechanical parameters that represent a fiber’s strength, extensibility, and stiffness. Importantly, the artificial fiber displayed the tenacity, elongation, and Young’s modulus of 508 MPa, 15%, and 21 GPa, respectively, which are comparable to those of the native spider silk. “We have offered an overall platform for mass production of native-like spider dragline silk. This platform would enable us to have broader industrial and biomedical applications for spider silk. Moreover, many other silk-like biomaterials such as elastin, collagen, byssus, resilin, and other repetitive proteins have similar features to spider silk protein. Thus, our platform should also be useful for their efficient bio-based production and applications,” concludes Professor Lee. This work is published on July 26 in the Proceedings of the National Academy of Sciences (PNAS) online.

The thermal fluctuation and elasticity of cell membranes, lipid vesicles, interacting with pore-forming peptides were reported by a research team at KAIST.
A research team from KAIST, consisted of Sung-Min Choi, Professor of Nuclear and Quantum Engineering Department, and Ji-Hwan Lee, a doctoral student in the Department, published a paper on the “thermal fluctuation and elasticity of lipid vesicles interacting with pore-forming peptides.” The paper was carried by Physical Review Letters, an internationally renowned peer-review journal on physics on July 16, 2010. Cell membranes, which consist of lipid bilayers, play important roles in cells as barriers to maintain concentrations and matrices to host membrane proteins. During cellular processes such as cell fission and fusion, the cell membranes undergo various morphological changes governed by the interplay between protein and lipid membranes. There have been many theoretical and experimental approaches to understand cellular processes driven by protein-lipid membrane interactions. However, it is not fully established how the membrane elastic properties, which play an important role in membrane deformation, are affected by the protein-membrane interactions. Antimicrobial peptides are one of the most common examples of proteins that modify membrane morphology. While the pore-forming mechanisms of antimicrobial peptides in lipid bilayers have been widely investigated, there have been only a few attempts to understand the mechanisms in terms of membrane elastic properties. In particular, the effects of pore formation on the membrane fluctuation and elastic properties, which provide key information to understand the mechanism of antimicrobial peptide activity, have not been reported yet. The research team reports the thermal fluctuation and elasticity of lipid vesicles interacting with pore-forming peptides, which were measured by neutron spin-echo spectroscopy. The results of this study are expected to pay an important role in understanding the elastic behavior and morphological changes of cell membranes induced by protein-membrane interactions, and may provide new insights for developing new theoretical models for membrane fluctuations which include the membrane mediated interaction between protein patches.

The 2010 International Forum on Electric Vehicle will be held at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, South Korea.
Universities, industries, and governments from the world gathered to make an important endeavor for the commercialization of electric vehicles that has emerged as a strong option to replace conventional cars with an internal combustion engine. With the potential benefit of electric cars, in view of environmental protection and less dependence of oil import, they still have limitations for the daily use in customers’ perspective. Electric cars are still very expensive to own with relatively short distance of driving with one charging and with the expensive and bulky nature of the batteries, in addition to the safety concerns with the Lithium batteries. The Korea Advanced Institute of Science and Technology (KAIST) will hold an international forum, at which it hopes to address a wide range of issues related to the development and commercialization of electric vehicles. The 2010 International Forum on Electric Vehicle will be held for three days at KAIST’s campus in Daejeon, South Korea, from June 17th to 19th, 2010. Internationally renowned speakers from Korea and overseas will present their views and conduct a discussion forum on the technology, market, and policy on electric vehicles. The event is open to the public. Major discussions, however, will take place on the second day, Friday, June 18, 2010, which will proceed with two sessions. In the first session, conference participants will discuss the topic of “policies and markets for electric vehicles,” and at the second session, they will take up the issue of “electric vehicle technologies.” Dr. Andrew Brown, president of SAE International and the executive director and chief technologist of Delphi, is scheduled to give a key note speech. The SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive, and commercial vehicle industries. Topics to be covered by Dr. Brown during his key note speech are, among other things, elements of market forces for hybrid electric vehicles, electric vehicles, or battery-powered vehicles; clean technologies necessary for sustainable development; pending issues facing the automotive industry to create a substantial share by electric cars and government aids to increase consumers’ buying power for expensive electric cars; technology innovation required for the improvement of batteries and power electronics; development of smart grids; and other key issues that would mature an ever-growing market for electric vehicles. President Nam Pyo Suh of KAIST will also deliver a key note remark on the overall accomplishments of online electric vehicle (OLEV) developed by KAIST. While stressing the OLEV’s technological breakthrough to succeed in the wireless in-motion power transfer through electromagnetic induction, President Suh will review the necessity of developing electric cars as a corresponding measure against climate changes and address the issues of battery weight and lifespan, charging time, and the limited amount of reserved Lithium. Dr. Steven Shladover from the California Partners for Advanced Transit and Highways (California PATH), established in 1986 in collaboration with the University of California in Berkeley and the California Transit, will attend the conference. California PATH is a multi-disciplinary program with universities statewide and cooperative projects with private industry, state and local agencies, and non-profit institutions to find solutions to the problems of California’s surface transportation systems through cutting edge research. California PATH once implemented a bold, innovative research project in the early 1990s in order to overcome the most difficult technical hurdle to reduce the heavy dependence of batteries for electric cars by adopting a non-contact transfer of electric power during vehicles’ movement. Despite the research declared as “unsuccessful” by California PATH, the implications of their innovative approach to solve an important issue inspired many researches subsequently followed—one of them is KAIST’s OLEV project. In addition, the Infineon Technologies AG, a leading semiconductor and system manufacturer based in Germany, which offers solutions for automotive, industrial and multimarket sectors for applications in communication and memory products, will come to the forum and present a paper on its expertise to develop the necessary components for electric vehicles. On the last day of the forum, all participants will have a chance to ride the Online Electric Vehicle (OLEV) at KAIST’s campus. For details of the event, please visit the website of “www.olev.co.kr/en/ifev or refer to the invitation attached herewith. About KAIST’s Online Electric Vehicle: The Online Electric Vehicle (OLEV) developed by KAIST is a dynamic plug-in electric car that receives electricity while running or stopping and thus acquired a complete mobility unlike other type of electric cars, whether hybrid or not. The OLEV reduces the size of a battery to one-fifth of the current battery installed in an electric car. Pure electric cars depend on a large bulky battery that has been a major obstacle to make the cars commercially accessible to the mass market. The OLEV gets charged wirelessly, a distinct difference to other dynamic plug-in electric cars including a tram or trolley, which directly picks up electricity from the road. To explain it further, the OLEV is electrified through power lines buried underground; when flowing low frequency of currents, an electric magnetic field is created around the underground power lines, and the pick-up gadget installed underbody of an electric vehicle converts the field into electricity; and the vehicle then uses electricity either for operation or stores it at a battery to be used for running the road that is not equipped with the power lines. The electric power generated from the underground travels to the surface of the road above 20cm-25cm. KAIST has succeeded to develop a commercial model of OLEV with a safe Electromagnetic Field (EMF), well below the international safeguard of 65mG. The actual model has been up and running at an amusement park in Seoul for the transportation of passengers. The non-contact charging method applied to the OLEV will accelerate the commercialization of electric cars by making a battery affordable and safer for a consumer.

President of Israel visited KAIST on June 9, 2010.
President of Israel, Shimon Peres, visited KAIST today on June 9, 2010 to witness the development of science and technology in Korea and explore ways of establishing collaboration and cooperation with industries and universities between Korea and Israel. President Peres led a delegation consisted of the Israeli Mister of Industry, Trade, and Labor, the Minister of Communication, and 60 business leaders from the top companies in the security, infrastructure, communication, high-tech, and water industries. Upon their arrival to the campus, the Israeli delegation was greeted by KAIST’s humanoid robot, “HUBO,” and then moved to its branch campus, IT Convergence Campus, for a ride of Online Electric Vehicle (OLEV) that has been developed by KAIST. The OLEV receives the necessary power through the cable lines buried underground, so it can be provided with a constant and continuous supply of electricity while running or stopping. Between roads and OLEVs is nothing but space. There is no electrical wires intricately crossed underbody of the electric car or above the road. The pick-up equipment installed beneath the body of the electric car collects magnetic fields created around the underground cables, which then converts the filed into electricity. The OLEV’s wireless, non-contact charging system made it possible for a battery currently used for hybrid or pure electric cars on the market to be smaller and cheaper. President Peres expressed a great interest in the technology applied to the OLVE, quoting, “the OLEV system is indeed very impressive.” He talked about efforts being made in Israel with respect to the development of electric cars. The country plans to replace the conventional transportation system with electric cars by constructing a network of battery exchange stations and roadside charge points which allow the cars to be charged whenever they are parked. “Despite the different approach taken by the two nations for the development of electric cars, I believe that transforming the automobile industry from combustion engine to electric system is the right direction we should all follow. Without addressing the current transportation system that heavily dependent on natural resources, we will not be able to promote “green growth on a global scale,” added President Peres. In addition to electric cars, President Peres took up a considerable portion of his time to exchange ideas on how to expand cooperative relations between universities in Korea and Israel, specifically in the area of space, biotechnology, nanotechnology, high-tech, renewable and alternative energy, and the EEWS initiatives that have been implemented by KAIST to find answers to global issues such as climate change and depletion of natural resources. The EEWS stands for energy, environment, water, and sustainability. In response, the president of KAIST pledged to set up a stronger and greater tie with research universities in Israel, particularly called for more collaboration between KAIST and Technion-Israel Institute of Technology. Also, the Israeli delegation had a tour for several Korean research and development centers in Daedeok Innopolis, located in the City of Daejeon, which is the 2nd largest science and research complex in Korea. Shimon Peres, the 9th president of Israel, held many of important government positions in Israel, among other things, Prime Minster and Minister of Defense. He won Nobel Peace Prize in 1994, together with Yitzhak Rabin and Yasser Arafat for the conclusion of a peace agreement, Oslo Accords, between Israel and Palestine Liberation Organization.

A Korean American businessman and his wife, Byiung Jun Park and Chunghi Hong, donated 10 million USD for the construction of the building. KAIST hosted an opening ceremony on May 11, 2010 for the new addition to its campus, called the Chunghi & Byiung Jun (BJ) Park KAIST Institute Building. The KI Building will serve as a hub for creative multidisciplinary researches. A Korean American businessman and his wife made a considerable contribution for the construction of the building, worth 10 million USD. KAIST called the building Byiung Jun (BJ) Park and Chunghi Hong in recognition of their contribution. Chairman Park was the founder of the Merchandise Testing Laboratory, a leading textile quality control multinational. It took 19 months to finish the construction of the KI Building with a total cost of 36 billion Korean won. The building consists of one basement and five ground floors. At the basement, there are clean room and equipment storage room; on the 2nd and 3rd floors, conference and exhibition halls; and on the rest of the floors, research labs and administration offices are to be located. KAIST’s eight integral research institutes will be placed inside the building: the BioCentury; Information Technology Convergence; Design of Complex Systems; Entertainment Engineering; the NanoCentury; Eco-Energy; Urban Space and Systems; and Optical Science and Technology. Approximately 230 professors from 25 departments of various academic fields will make the KI Building home for study and research. The KI Building will play a great role in producing world-class convergence research works by KAIST researchers and professors, thereby making a contribution to the improvement of national competitiveness. Vice President of KI Building, Sang-Soo Kim, said, “There has been no such place for us to concentrate research manpower and equipment scattered around the campus. By having all the necessary resources at one place will allow us to conduct convergence researches more efficiently and effectively. I’d like to express my appreciation for the Ministry of Education and Science and Technology as well as Chairman Byiung Jun (BJ) Park, who gave us tremendous supports in the process of constructing the KI Building.” “The building’s inside has a unique office structure, getting rid of walls or partitions between institutes or departments, to stimulate an environment conducive to convergence researches. We hope to present a new model for creative multidisciplinary researches through a selective and focused approach to be facilitated by institutes at the KI Building,” added by the vice president.

1,180 meters of fence on campus facing Gap-Chun River will be gone by June 2010.
KAIST and the City of Daejeon have taken on a project to remove a stretch of fence on campus that faces Gap-Chun River, making the campus accessible to all citizens and visitors. The work will last for three months beginning on April 5th and throughout June 2010. Gradually, KAIST plans to remove the entire fence surrounding the campus within a few years. The city government has encouraged government and public organizations in Daejeon to open up their public space to citizens and visitors as part of its initiatives to reach out to local communities. As of December 2008, seven public organizations have completed to rid of their boundary markers, and eight more organizations will make their gardens and campus available to the public by the end of this year. All the expenses related to the removal of the fence will be borne by the city government. At the place where the fence is knocked down will become a park so that neighbors and visitors can come and rest. A school official said, “This is an important campaign for us because it promotes more exchanges between the university and local community. Our campus has rich green foliage, and visitors will surely enjoy it. By opening up our campus to the public, we hope to return to the society what we have received as a public institution and create a forum where art, science, and technology meet together.” In addition to the removal of the fence, KAIST and the city government will install flowerbeds, health facilities, and walking trails for the citizens.
