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。

Zanamivir and oseltamivir bind differently at the neuraminidase catalyticsite and this contributes to different drug resistance profiles.
扎那米韦和奥塞·米韦结合在神经氨酸酶的不同催化位点，这就导致了这种耐药情况不同的发生。
