Membrane-associated phospholipase A2 was purified to homogeneity from human spleen. The enzyme was solubilized from the particulate fraction by the addition of KBr, and purified by reverse-phase high-performance liquid chromatography. The estimated molecular weight of the enzyme was 14,000. The enzyme had a pH optimum around 9.5, required the presence of Ca2+ for its activity, and hydrolyzed phosphatidylethanolamine more efficiently than phosphatidylcholine.
