Abstrakt: Cytosolic phospholipase A2 (cPLA2) is normally located in the cytosol, but in response to cellular activation the enzyme binds to the membrane at the lipid/water interface where it catalyzes the hydrolysis of the sn-2 ester of arachidonate-containing phospholipids. Synthetic phospholipid vesicle systems have been used in kinetic and mechanistic analyses of cPLA2, but these systems result in a rapid loss of enzyme activity. In the present research, covesicles of 1,2-dimyristoyl-sn-glycero-3-phosphomethanol (DMPM) containing (Copyright 1999 Academic Press.)
