Comments

FUNCTION: Hydrolysis of phosphatidylcholine with phospholipase A2 (EC 3.1.1.4) and phospholipase A1 (EC 3.1.1.32) activities (By similarity).
CATALYTIC ACTIVITY: Phosphatidylcholine + H₂O = 2-acylglycerophosphocholine + a carboxylate.
CATALYTIC ACTIVITY: Phosphatidylcholine + H₂O = 1-acylglycerophosphocholine + a carboxylate.
COFACTOR: Calcium (By similarity).
SUBUNIT: Homodimer (By similarity).
SUBCELLULAR LOCATION: Cell outer membrane. Note=One of the very few enzymes located there (By similarity).
SIMILARITY: Belongs to the phospholipase A1 family.
