IUBMB Enzyme Nomenclature


Accepted name: glycerol-3-phosphate 2-O-acyltransferase

Reaction: an acyl-CoA + sn-glycerol 3-phosphate = CoA + a 2-acyl-sn-glycerol 3-phosphate

Other name(s): sn-2-glycerol-3-phosphate O-acyltransferase; glycerol-3-phosphate O-acyltransferase (ambiguous)

Systematic name: acyl-CoA:sn-glycerol 3-phosphate 2-O-acyltransferase

Comments: 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.
