Abstract

Secreted phospholipases A(2) have similar catalytic sites, but vastly different interfacial binding surfaces that modulate their binding affinity for different kinds of phospholipid vesicles by several orders of magnitude. The structure/function principles that dictate both the differential interfacial binding and the physiological function of these enzymes are beginning to be unraveled.

摘要

分泌型磷脂酶A(2)具有相似的催化位点,但界面结合表面却大不相同,这些表面可将它们对不同种类磷脂囊泡的结合亲和力调节几个数量级。决定这些酶的差异界面结合和生理功能的结构/功能原理正开始被揭示。
