由于substrate的形状与active site的形状高度契合(fit),因此substrate能够与active site特异性地结合,形成酶-底物复合物(enzyme-substrate complex)。Enzyme-substrate complex形成会涉及到一些化学基团(chemical groups)之间的相互作用。 诱导契合模型(induced fit model)认为:当substrate结合到active site后,酶的结构会发生...
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...

Induced fit mode是指当substrate结合到active site后,enzyme will change its structure,使得substrate和active site的结合更加地紧密,提高了酶的催化能力。 我们接下来讲一下chemical reaction. 对于一个化学反应AB + CD → AC + BD, AB和CD是这个酶的substr...

(~6.0) permits continuous measurement of enzymatic activity. Thiols such as DTT or 2-mercaptoethanol should be avoided in assays utilizing resorufin-based substrates. Our Amplex Red peroxidase substrate (A12222,A22177;Substrates for Oxidases, Including Amplex ...
必应词典为您提供enzyme-substratemolecule的释义,网络释义: 酵素受质结合分子;酶受质结合分子;
An enzyme will interact with only one type of substance or group of substances, called thesubstrate, to catalyze a certain kind of reaction. Because of this specificity, enzymes often have been named by adding the suffix “-ase” to the substrate’s name (as inurease, which catalyzes the ...
