摘要：

Hydrolysis of planar phospholipids catalyzed by honey bee venom phospholipase A(2) (bvPLA(2)) was studied. Experiments demonstrated that Ca2+ ions mediated between the lipids and bvPLA(2), induced reorientation of bvPLA(2), and activated hydrolysis. One of the hydrolysis products, fatty acids, was desorbed, and the other one, lysophospholipids, self-organized at the interface.
