Enzyme Commission Primary Name: glycerol-3-phosphate 2-O-acyltransferase

Enzyme Commission Synonyms: sn-2-glycerol-3-phosphate O-acyltransferase, glycerol-3-phosphate O-acyltransferase (ambiguous)

Enzyme Commission Summary:
A membrane- associated enzyme required for suberin or cutin synthesis in plants. Active with a wide range of acyl-CoA substrates (C16:0-C24:0). The enzyme from some sources has much higher activity with ω-oxidized acyl-CoAs. Some enzymes are bifunctional and have an additional phosphatase activity producing sn-2-monoacylglycerols. Can also catalyse the reaction of EC, glycerol-3-phosphate 1-O-acyltransferase, but less well.
