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...

酶的活性位点中的氨基酸排布方式刚好使得能其与底物的某些化学基团发生结合,形成enzyme–substrate complex。 在enzyme–substrate complex形成之后,酶的活性位点结构会发生稍微的改变,导致反应的进行。活性位点的其他氨基酸残基行使催化的功能,不同的酶其活性位点的氨基酸排列不同,因此一种酶只能催化一种化学反应或一类型...

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 ...
