Discovery of Redox-Switch of KEenzyme Involved in N-Butanol Biosynthesis
Research teams at KAIST and Kyungpook National University (KNU) have succeeded in uncovering the redox-switch of thiolase, a key enzyme for n-butanol production in Clostridium acetobutylicum, one of the best known butanol-producing bacteria.
Biological n-butanol production was first reported by Louis Pasteur in 1861, and the bioprocess was industrialized usingClostridium acetobutylicum. The fermentation process by Clostridium strains has been known to be the most efficient one for n-butanol production. Due to growing world-wide issues such as energy security and climate change, the biological production of n-butanol has been receiving much renewed interest. This is because n-butanol possesses much better fuel characteristics compared to ethanol, such as higher energy content (29.2 MJ/L vs 19.6 MJ/L), less corrosiveness, less hygroscopy, and the ease with which it can be blended with gasoline and diesel.
In the paper published in Nature Communications, a broad-scope, online-only, and open access journal issued by the Nature Publishing Group (NPG), on September 22, 2015, Professor Kyung-Jin Kim at the School of Life Sciences, KNU, and Distinguished Professor Sang Yup Lee at the Department of Chemical and Biomolecular Engineering, KAIST, have proved that the redox-switch of thiolase plays a role in a regulation of metabolic flux in C. acetobutylicum by using in silico modeling and simulation tools.
The research team has redesigned thiolase with enhanced activity on the basis of the 3D structure of the wild-type enzyme. To reinforce a metabolic flux toward butanol production, the metabolic network of C. acetobutylicum strain was engineered with the redesigned enzyme. The combination of the discovery of 3D enzyme structure and systems metabolic engineering approaches resulted in increased n-butanol production in C. acetobutylicum, which allows the production of this important industrial chemical to be cost competitive.
Professors Kim and Lee said, "We have reported the 3D structure of C. acetobutylicum thiolase-a key enzyme involved in n-butanol biosynthesis, for the first time. Further study will be done to produce butanol more economically on the basis of the 3D structure of C. acetobutylicum thiolase."
This work was published online in Nature Communications on September 22, 2015.

Figure 1: A redox-switch of thiolase involves in butanol biosynthesis in Clostridium acetobutylicum. Thiolase condenses two acetyl-CoA molecules for initiating four carbon flux towards butanol.
Figure 2: Thiolase catalyzes the condensation reaction of acetyl-CoA to acetoacetyl-CoA. Two catalytic cysteine residues at 88th and 378th are oxidized and formed an intermolecular disulfide bond in an oxidized status, which results in inactivation of the enzyme for n-butanol biosynthesis. The intermolecular disulfide bond is broken enabling the n-butanol biosynthesis, when the environment status is reduced.

Professor Woontack Woo Demonstrates an Optical Platform Technology for Augmented Reality at Smart Cloud Show
Professor Woontack Woo of the Graduate School of Culture Technology at KAIST participated in the Smart Cloud Show, a technology exhibition, hosted by the university’s Augmented Human Research Center and presented the latest development of his research, an optical platform system for augmented reality.
This event took place on September 16-17, 2015 at Grand Seoul Nine Tree Convention Center in Seoul.
At the event, Professor Woo introduced a smart glass with an embedded augmented reality system, which permits remote collaboration between an avatar and the user’s hand.
The previous remote collaboration was difficult for ordinary users to employ because of its two-dimensional screen and complicated virtual reality system.
However, with the new technology, the camera attached to artificial reality (AR) glasses recognizes the user’s hand and tracks it down to collaborate. The avatar in the virtual space and the user’s hand interact in real space and time.
The key to this technology is the stable, real-time hand-tracking technique that allows the detection of the hand’s locations and the recognition of finger movements even in situations of self-occlusion.
Through this method, a user can touch and manipulate augmented contents as if they were real-life objects, thereby collaborating remotely with another user who is physically distant by linking his or her movements with an avatar.
If this technology is adopted widely, it may bring some economic benefits such as increased productivity due to lower costs for mobility and reduction in social overhead costs from the decrease in the need of traveling long distance.
Professor Woo said, “This technology will provide us with a greater opportunity for collaboration, not necessarily restricted to physical travelling, which can be widely used in the fields of medicine, education, entertainment, and tourism.”
Professor Woo plans to present his research results on hand-movement tracking and detection at the 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI 2015), to be held on October 28-30, 2015, at Kintex in Goyang, Korea.
He will also present a research paper on remote collaboration at the ICAT-EGVE 2015 conference, the merger of the 25th International Conference on Artificial Reality and Telexistence (ICAT 2015) and the 20th Eurographics Symposium on Virtual Environments (EGVE 2015), which will take place on October 28-30, 2015 at the Kyoto International Community House, Kyoto, Japan.

KAIST's Mathematician Reveals the Mechanism for Sustaining Biological Rhythms
Our bodies have a variety of biological clocks that follow rhythms or oscillations with periods ranging from seconds to days. For example, our hearts beat every second, and cells divide periodically. The circadian clock located in the hypothalamus generates twenty-four hour rhythms, timing our sleep and hormone release. How do these biological clocks or circuits generate and sustain the stable rhythms that are essential to life?
Jae Kyoung Kim, who is an assistant professor in the Department of Mathematical Sciences at KAIST, has predicted how these biological circuits generate rhythms and control their robustness, utilizing mathematical modeling based on differential equations and stochastic parameter sampling. Based on his prediction, using synthetic biology, a research team headed by Matthew Bennett of Rice University constructed a novel biological circuit that spans two genetically engineered strains of bacteria, one serves as an activator and the other as a repressor to regulate gene expression across multiple cell types, and found that the circuit generates surprisingly robust rhythms under various conditions.
The results of the research conducted in collaboration with KAIST (Korea Institute of Science and Technology), Rice University, and the University of Houston were published in Science (August 28, 2015 issue). The title of the paper is "Emergent Genetic Oscillations in a Synthetic Microbial Consortium" .
The top-down research approach, which focuses on identifying the components of biological circuits, limits our understanding of the mechanisms in which the circuits generate rhythms. Synthetic biology, a rapidly growing field at the interface of biosciences and engineering, however, uses a bottom-up approach.
Synthetic biologists can create complex circuits out of simpler components, and some of these new genetic circuits are capable of fluctuation to regulate gene production. In the same way that electrical engineers understand how an electrical circuit works as they construct batteries, resistors, and wires, synthetic biologists can understand better about biological circuits if they put them together using genes and proteins. However, due to the complexity of biological systems, both experiments and mathematical modeling need to be applied hand in hand to design these biological circuits and understand their function.
In this research, an interdisciplinary approach proved that a synthetic intercellular singling circuit generates robust rhythms to create a cooperative microbial system. Specifically, Kim's mathematical analysis suggested, and experiments confirmed, that the presence of negative feedback loops in addition to a core transcriptional negative feedback loop can explain the robustness of rhythms in this system. This result provides important clues about the fundamental mechanism of robust rhythm generation in biological systems.
Furthermore, rather than constructing the entire circuit inside a single bacterial strain, the circuit was split among two strains of Escherichia coli bacterium. When the strains were grown together, the bacteria exchanged information, completing the circuit. Thus, this research also shows how, by regulating individual cells within the system, complex biological systems can be controlled, which in turn influences each other (e.g., the gut microbiome in humans).

KAIST Develops Fiber-Like Light-Emitting Diodes for Wearable Displays
Professor Kyung-Cheol Choi and his research team from the School of Electrical Engineering at KAIST have developed fiber-like light-emitting diodes (LEDs), which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Traditional wearable displays were manufactured on a hard substrate, which was later attached to the surface of clothes. This technique had limited applications for wearable displays because they were inflexible and ignored the characteristics of fabric.
To solve this problem, the research team discarded the notion of creating light-emitting diode displays on a plane. Instead, they focused on fibers, a component of fabrics, and developed a fiber-like LED that shared the characteristics of both fabrics and displays.
The essence of this technology, the dip-coating process, is to immerse and extract a three dimensional (3-D) rod (a polyethylene terephthalate fiber) from a solution, which functions like thread. Then, the regular levels of organic materials are formed as layers on the thread.
The dip-coating process allows the layers of organic materials to be easily created on the fibers with a 3-D cylindrical structure, which had been difficult in existing processes such as heat-coating process. By controlling of the withdrawal rate of the fiber, the coating's thickness can also be adjusted to the hundreds of thousandths of a nanometer.
The researchers said that this technology would accelerate the commercialization of fiber-based wearable displays because it offers low-cost mass production using roll-to-roll processing, a technology applied to create electronic devices on a roll of flexible plastics or metal foils.
Professor Choi said, “Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics. We hope we can lower the barrier of wearable displays entering the market.”
The lead author of the published paper, Seon-Il Kwon, added, “This technology will eventually allow the production of wearable displays to be as easy as making clothes.”

Professor Sang-Min Bae Receives the 2015 Red Dot Design Award
Professor Sang-Min Bae and his research team from the Industrial Design Department of KAIST have received three awards from the 2015 Red Dot Design Award: the Best of the Best Award and two Design Concept Awards.
Being one of the most prestigious international design awards, the Red Dot Design Award serves to identify good design concept and innovation that will be the precursors of tomorrow’s great product. Its annual award ceremony will take place on September 25, 2015, at the Red Dot Design Museum in Singapore.
This year, the Award received 4,680 entries from 61 countries, and only the top 5.7% of them was able to garner the awards. In addition to two Red Dot Design Concept Awards, Professor Bae’s team won the Best of the Best Award, coming through a four hundred to one competition.
Awarded the Best of the Best Award, Boxchool is a modular classroom built on shipping containers whose aim is to give underprivileged children equal opportunities for learning. Jointly designed with an IT corporation in Korea, SK Telecom, the container is also a smart classroom.
Boxchool received the Best of the Best Award in recognition of its contribution to giving an equal learning opportunity to needy children, as well as its environmental characteristics.
The research team strengthened the mobility of the container and creatively addressed problems associated with using containers as classrooms such as insulation and inadequate space in environments which hamper teaching. The modular classroom can function in any setting since it can generate electricity from installed solar panels. The rainwater utilization system allows autonomous operation of the classroom.
The team earned the Red Dot Design Concept Award for a self-generating interactive tent, which was jointly designed with Kolon Sport, a Korean outdoor products company, as an industry-university cooperation project. The interactive tent differs from conventional tents by adding features that allow users to engage with the environment. For example, the installed organic solar cells allowed users to have prolonged outdoor activities by supplying electricity generated therefrom. Users can also enjoy greater ventilation. This permits the tent to be utilized as a temporary residence in the third world.
Another recipient of the Red Dot Design Concept Award, Snow Energy is a portable self-generating lamp and charger, which contains a thermo-element, generating electricity from temperature difference. Electricity is generated by pouring hot water inside a tank and cold water into a neighboring space. Snow Energy, which is sustainable and eco-friendly, will be especially helpful during outdoor activities when there is no electricity available.
Professor Bae's research team, ID+IM, has endeavored to address inequality and philanthropy through two projects, the Nanum (a Korean word to mean “sharing”) and the Seed Projects. Since 2005, they have received internationally recognized awards more than 40 times.
