Enzymes are protein molecules whose role is to catalyse and control the chemical reactions that take place in living organisms. They perform this role in ways that differ from reaction to reaction but, in every instance, catalysis proceeds through the formation of complexes between the enzyme and ...
Enzymes versus catalysts: a question of scale? For many industrial processes, biological catalysis is more cost effective than chemical catalysis. But doubts over how easy enzymes are to use is hampering uptake, Andrew Turley reports from InformEx in San Francisco.(Infomex report)...
Enzymes are biological catalysts, it has a specificity and high catalytic efficiency characteristics, often at room temperature and low-concentration complex biochemical reactions. No enzymes, then you have all life activities of living organisms. Enzyme engineering research on enzyme production and ...

Enzymes are nature's own catalysts and fundamental for life, as they catalyze essentially all biological processes. Compared to inorganic catalysts, however, their structure and function is immensely more complicated. Computational modeling has played an increasing role in elucidating enzyme mechanisms, as...
aNature's catalysts -- enzymes -- function highly selectively to accelerate the rate of chemical reactions in biological systems. Enzymes also can limit reactivity toward a particular substrate and limit chemical conversion to a single desired product. 自然的催化剂 -- 酵素 -- 高度有选择性地加速化...
and it was rightly thought that an entirely new work would be better than an attempt by an alien hand to bring Bayliss up-to-date. Bayliss's main thesis was that enzymes act as colloidal catalysts and combine with their substrates and other substances by adsorption, “so that the action of...
Enzymes and ribozymes constitute two biological catalysts. The activity of many natural enzymes is regulated by the binding of ligands that have different structures than their substrates; these ligands are consequently called allosteric effectors. In most allosteric enzymes, the allosteric binding site ...
All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these reactions proceed spontaneously, in the absence of enzymes – minutes, hours, days? And why even pose the question?
