Lock and key model应该很好理解,substrate are exactly complimentary to enzyme active site.他们是一个完美的契合结构,像钥匙和锁一样。 Induced fit mode是指当substrate结合到active site后,enzyme will change its structure,使得substrate和active site的结合...
In addition to the commonly used chromogenic substrates, including BCIP, NBT and X-gal (see below), we have developed a fluorogenic ELF 97 phosphatase substrate that fluoresces only weakly in the blue range. Upon enzymatic cleavage, however, this substrate...

labor-intensive, and often not straightforward. Such approaches include the use of genetic and pharmacologic perturbations11, substrate-trapping mutants12, affinity purification-mass spectrometry13, utilizing peptide14or protein arrays15, tagging the client proteins by substrate analogs using engineered enzym...
Moreover, the front-face optics in many microplate readers allows researchers to use more concentrated solutions, which may both improve the linearity of the kinetics and reduce inner-filter effects. When the spectral characteristics of the substrate and its metab...
2.5.U2 Enzyme catalysis involves molecular motion and the collision of substrates with the active site. 酶促反应中,反应物称为底物(substrate),生成物称为产物(product)。酶的作用就是把底物结合到一个特殊的结构中,这个结构叫活性位点(active site)。底物和酶结合后的复合物称为enzyme–substrate complex,此时...
Structural and biochemical mechanism of short-chain enoyl-CoA hydratase (ECHS1) substrate recognition The study of ECHS1 functional mechanism provides a theoretical basis for subsequent work focused on determining the role of ECHS1 deficiency (ECHS1D) in the occurrence of diseases such as cardiomyopat...
is linked to an enzyme prior to reaction with the antigen and is then followed by assessment of the enzyme conjugated antibody–antigen reaction or activity upon incubation with the enzyme-specific substrate producing a detectable signal, which is mainly a change in the color of the substrate. ...
and use of anyenzyme. These so-calledenzyme assaysfocus on the detection of the chemical transformation of a test substrate, on which an (enantio) selective reaction is often desired for use in white biotechnology.1,2Detecting catalysis is important because the mere presence of the enzyme, for...
