ActivationCooperativityEnzyme kineticsThe rate of an enzymatic reaction may be changed by a moderator. Usually, the effect is to reduce the rate, and this is called inhibition. Sometimes the rate of enzyme reaction is raised, and this is called activation. Not only enzyme activation is subject ...

[Factors influencing enzyme reaction rates (enzyme kinetics): enzyme inhibition and activation] 来自 NCBI 喜欢 0 阅读量: 26 作者: T Sanner 摘要: The reaction of glutamate dehydrogenase and glutamate (gl) with NAD+ and NADP+ has been studied with stopped-flow techniques. The enzyme was in all...
In enzymatic reactions, xenobiotics are initially activated by activation enzymes. The generated reactive metabolites then undergo detoxification enzyme–catalyzed reactions, before they are ready for excretion from the body. Hence, induction or inhibition of metabolic enzymes has a significant impact on th...
In addition, the four basic mechanisms of reversible enzyme inhibition, the topic of irreversible enzyme inhibition and enzyme activation as well as special cases of drug action on intracellular enzymes are discussed. Enzymes are nature's ubiquitous catalysts mediating thousands of biochemical reactions ...

Using this approach, several cycles of externally controlled enzyme inhibition and activation are successfully demonstrated. This principle of responsive enzyme nanodevices may be used to regulate other types of enzymes and to introduce feedback or feed-forward control loops. 展开 ...
Theaflavin-3,3′-digallate from black tea blocks the nitric oxide synthase by down-regulating the activation of NF-κB in macrophages Nitric oxide (NO) plays an important role in inflammation and also in multiple stages of carcinogenesis. We investigated the effects of various tea polyphe... HJ...
However, the molecular mechanisms for activation and regulation of DUOX1 remain mostly unclear. Here, I present cryo-EM structures of the mammalian DUOX1–DUOXA1 complex, in the absence and presence of substrate NADPH, as well as DUOX1–DUOXA1 in an unexpected dimer-of-dimers configuration. ...
