Function
function
Acylhydrolase that catalyzes the hydrolysis of phosphatidylcholine at the sn-1 position. Moderate activity toward phosphatidylcholine (PC), monogalactosyldiacylglycerol (MGDG), digalactosyldiacylglycerol (DGDG) and triacylglycerol (TAG).
Catalytic activity
- 1,2-dihexadecanoyl-sn-glycero-3-phosphocholine + H2O = 2-hexadecanoyl-sn-glycero-3-phosphocholine + H+ + hexadecanoateThis reaction proceeds in the forward direction.
- a 1,2-diacyl-3-O-(beta-D-galactosyl)-sn-glycerol + H2O = a fatty acid + an acyl-3-O-(beta-D-galactosyl)-sn-glycerol + H+This reaction proceeds in the forward direction.
- 1,2-diacyl-3-O-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-sn-glycerol + H2O = a fatty acid + acyl-3-O-[alpha-D-galactosyl-(1->6)-beta-D-galactosyl]-sn-glycerol + H+This reaction proceeds in the forward direction.
