by using rat-liver mitochondria containing labeled phosphatidylethanolamine and inactivated phospholipase a2 as substrate source , and mitochondria containing unlabeled substrate and active enzyme , it is shown that hydrolysis of phosphatidylethanolamine by mitochondrial phospholipase a2 proceeds nearly entirely via intramembrane enzyme action .
