7.6.2 Describe the induced-fit model. Initially the substrate does not fit perfectly into the active site of the enzyme. When the substrate binds to the active site, this changes the shape of the active site and only then does it perfectly fit the substrate. As the substrate binds it chan...
Re:Enzyme as a catalyst «Reply #2 on:August 16, 2005, 11:54:36 AM » True. But if you were to examine closely an enzyme, for example a 'modified' version of Serine Protease - alpha chymotrypsin - yo'd get to see that the lysine and arginine residue are side by side and do...
Enzymes are basically protein, acting as a catalyst to streamline chemical processes and support our body’s daily functioning It is partially self-created and partially taken from food we eat. Our enzyme bank shrinks as part of our aging process, which might affect our health status. 消化酶是...
Regio- and stereo-selective synthesis of polysaccharides and oligosaccharides has been achieved by using glycosyl fluorides as substrates for cellulases. This methodology has successfully been applied to the first synthesis of cellulose via a non-biosynthetic pathway as well as to a selective preparation...

Results Preparation of the bifunctional MCN (OMCN-1). The preparation of the bifunctional catalyst is shown in Fig. 1. Briefly, ethylenediamine (EDA) and carbon tetrachloride (CTC) as carbon and nitrogen sources respectively, were first introduced and polymerized in the porous channels of ...
工业生产或实验室条件下,如果需要发生化学反应,一般通过施加高温、高压、极端pH、提高反应物的浓度(增加碰撞collision概率)或是使用无机催化剂(inorganic catalysts),而在生物体中,许多的化学反应都是在比较温和的条件下自发的进行,并且是在需要的时候进行,这得益于酶(biological catalyst, increase the rate by lowering...
We use this system to perform the directed evolution of a phosphotriesterase (a bioremediation catalyst) caged in GSBs and isolate a 20-fold faster mutant in less than one hour. We thus establish a practically undemanding method for ultrahigh-throughput screening that results in functional hybrid ...
