Mammals possess five biotin-dependentenzymesthat play key roles in important metabolic pathways; acetyl-CoA carboxylase-1 (synthesis of malonyl-CoA for fatty acid synthesis), acetyl-CoA carboxylase-2 (synthesis of malonyl-CoA to regulate β-oxidation of fatty acid synthesis),pyruvate carboxylas...
The A. thaliana mutant line carrying a T-DNA insertion in the CYP98A3 gene produced a much reduced amount of coumarins (∼3% of that in the wild-type root) indicating that 3′-hydroxylation of the 4-coumarate unit within the phenylpropanoid pathway by this P-450 is critically important ...
Acetyl-CoA is an important metabolic intermediate and serves as an acetylation precursor for the biosynthesis of various value-added acetyl-chemicals. Acetyl-CoA can be produced from glucose, acetate, or fatty acids via metabolic pathways in Escheri
Important examples of modular PKS products include: erythromycin, rifamycin and fidaxomicin (antibacterials); amphotericin and nystatin (antifungals); rapamycin and FK-506 (immunosuppressants); spinosyns (insecticides) and avermectins (insecticides and anthelmintics). These remarkable multienzymes employ ...

It is important to highlight that, particularly in the presence of BG11-N-P + A, the acetyl-CoA flow was mainly diverted to the PHB biosynthetic pathway. Fig. 1 Overview of the polyamine-proline-glutamate pathways connected to the tricarboxylic acid (TCA) cycle and related biosynthetic...

Eliminate contention for the cache between the instruction fetch/decode unit and the execution unit, which is important to the pipelining of instructions(消除指令获取/解码单元和执行单元之间对缓存的争用,这对指令的流水线很重要) 4.1. 计算平均访问时间 我们假设第一级的访问时间为T1,第二季访问时间T2,第...
7.11.5.3.1 Acyl-CoAs (or acyl-ACPs) as electrophiles: True Claisen condensations (thiolases) The Claisen condensation – strictly the condensation of two esters with the concomitant release of one of the constituent alcohol moieties – is arguably the most important carbon–carbon bond-formin...
MK plays an important role in microbial synthesis of terpenoids as it catalyzes the first committed step toward IPP biosynthesis after HMGR. Engineering the MVA pathway in E. coli involves the incorporation of the MVA pathway in two modules. The upper module consists of ACT, HMGS, and HMGR. ...
