● 北京大学邹鹏特聘研究员讲座通知(2016-4-28)
题目:Mapping the Subcellular Proteome via APEX Labeling
报告人:邹鹏 博士(北京大学化学与分子工程学院特聘研究员)
主持人:刘进 特聘研究员
时间:2016年4月28日(周四)上午10:00
地点:工学院1号楼210会议室
报告内容摘要:
Dr Zou will introduce a new technology that offers spatially-resolved proteomic maps of living cells. The method relies on an engineered peroxidase enzyme, APEX, that biotinylates nearby proteins, which are subsequently purified and identified by mass-spec. We used this approach to identify proteins residing within the human mitochondrial matrix and the inter-membrane space. The labeling was exceptionally specific and led to the discovery of several novel mitochondrial proteins, including two key players in the heme biosynthesis pathway, which challenged the textbook model of how this pathway operates. The specificity of live-cell peroxidase-mediated proteomic mapping combined with its ease of use offers biologists a powerful tool for understanding the molecular composition of living cells.

● 澳大利亚昆士兰大学Lars Nielsen教授讲座通知(2015-3-12)
题目:Genome scale metabolic and regulatory network modelling in higher eukaryotes
报告人:Lars Nielsen, Professor
主持人:Steven Feng Chen (陈峰), Professor
时间:2015年3月16日(周一)10:00
地点:工学院1号楼212会议室
报告内容摘要:
Implicit in the collection of high-throughput data is an assumption that computational models ultimately will facilitate biological discovery, reconciliation of heterogeneous data types, identify inconsistencies and enable the systematic generation of hypotheses. Current naïve statistically models falls well short of this ambition, while the use of the conventional dynamic models of physics suffers from our inability to accurately determine in vivo parameters. Constraint based models use stoichiometry, thermodynamics, physical capacity constraints and regulation to define feasible solution spaces, which can then be explored using a range tools to infer network behaviour. The framework has proven surprisingly powerful in its ability to predict the behaviour of natural as well as engineered networks in microbes.
Higher eukaryotes present additional challenges in the form of (a) compartmentalised metabolism with difficult to identify intracellular transporters and pathway duplication, (b) complex genome regulation, (b) multicellularity and associated difficulty in defining objectives, and (d) difficulty of reliable manipulation and analysis at cellular level. However, the same challenges that make higher eukaryotic systems less tractable also makes the potential advantage of model based analysis far greater. In this presentation, I will discuss a range of mathematical and experimental approaches we use to identify and constrain the degrees of freedom in animal and plant genome scale models to make them more tractable. The aim is to - at a minimum - make explicit the assumptions made in more practical, reduced models and - ideally - develop controls for these assumptions.

● 美国俄亥俄州立大学杨尚天(Shang-Tian Yang)教授讲座通知(2012-12-11)
题目:Engineering Clostridial Fermentation for Biofuels and Chemicals Production
报告人:Shang-Tian Yang, Professor
时间:2013年1月8日14:00
地点:工学院1号楼210会议室
报告内容摘要:
This presentation will focus on the recent progress in metabolic engineering of Clostridia for economical production of biofuels, including butanol from renewable biomass. Butanol is an important industrial solvent and potentially a better transportation fuel than ethanol. Currently, butanol is almost exclusively produced via petrochemical routes. Biobutanol will have a great potential to compete with ethanol as a transportation fuel when its production cost is reduced by using advanced fermentation technologies such as metabolically engineered Clostridia mutants. Conventional acetone-butanol-ethanol (ABE) fermentation by Clostridium acetobutylicum or C. beijerinkii is severely limited by its poor butanol yield (<0.25 g/g glucose), low productivity (<0.5 g/L栠), low final butanol concentration (<15 g/L), and poor process stability. Recently, we have developed several metabolically engineered mutant strains of clostridia for butanol production. A novel solventogenic Clostridium was developed by introducing butanol biosynthesis pathway and blocking acid producing pathways in non-solventogenic acid-forming Clostridium tyrobutyricum which has relatively simple metabolic pathways with high flux toward butyryl-CoA, the precursor for butanol biosynthesis, and high butanol tolerance. A high butanol titer of >16 g/L with a high butanol yield of 0.33 g/g substrate were obtained in batch fermentation. In addition, we have also developed a mutant strain of Clostridium acetobutylicum with high butanol tolerance and productivity through evolutionary engineering in a fibrous bed bioreactor (FBB). The high butanol tolerant strain JB200 can produce up to 21 g/L butanol in conventional free-cell fermentation and 28.2 g/L butanol in the FBB fermentation. When the mutant strain is used in fermentation coupled with continuous gas stripping for in situ butanol recovery, high butanol productivity and yield can be achieved with an extremely high butanol titer of >150 g/L in the gas stripping condensate that can be easily purified with a low energy input.
