The catalytic center of an enzyme is composed of a set of amino acids whose three-dimensional arrangement forms the "active-site" that allows them to efficiently bind and modify the substrate.
酶的催化中心是由一组氨基酸组成,其三维结构形成活性位点,允许它高效地结合或修饰底物。

Covalent catalysis involves the substrate forming a transient covalent bond with residues in the activesite or with a cofactor.
共价催化涉及底物与活性位点中的残基或与辅因子形成瞬时共价键。

It's a very activesite and the 13 year old mentor I chatted with in testing the service was very well spoken.
