Reactions
2-lysophosphatidylcholine + H(2)O = glycerophosphocholine + a carboxylate.
General function:
Involved in phospholipase activity
Specific function:
Has broad substrate specificity including hydrolysis of phosphatidylcholine with phospholipase A2 (EC 3.1.1.4) and phospholipase A1 (EC 3.1.1.32) activities. Strong expression leads to outer membrane breakdown and cell death; is dormant in normal growing cells. Required for efficient secretion of bacteriocins

Reactions
Phosphatidylcholine + H(2)O = 2-acylglycerophosphocholine + a carboxylate.
Phosphatidylcholine + H(2)O = 1-acylglycerophosphocholine + a carboxylate.
General function:
Involved in transferase activity, transferring acyl groups
Specific function:
Plays a role in lysophospholipid acylation. Transfers fatty acids to the 1-position via an enzyme-bound acyl-ACP intermediate in the presence of ATP and magnesium. Its physiological function is to regenerate phosphatidylethanolamine from 2-acyl-glycero-3-phosphoethanolamine (2-acyl-GPE) formed by transacylation reactions or degradation by phospholipase A1

Reactions
Acyl-[acyl-carrier-protein] + O-(2-acyl-sn-glycero-3-phospho)ethanolamine = [acyl-carrier-protein] + O-(1-beta-acyl-2-acyl-sn-glycero-3-phospho)ethanolamine.
ATP + an acid + [acyl-carrier-protein] = AMP + diphosphate + acyl-[acyl-carrier-protein].
