IUBMB Enzyme Nomenclature


Accepted name: acyl phosphate:glycerol-3-phosphate acyltransferase

Reaction: an acyl phosphate + sn-glycerol 3-phosphate = a 1-acyl-sn-glycerol 3-phosphate + phosphate

Other name(s): plsY (gene name); G3P acyltransferase; GPAT; lysophosphatidic acid synthase; LPA synthase

Systematic name: acyl phosphoate:sn-glycerol 3-phosphate acyltransferase

Comments: The enzyme, found in bacteria, catalyses a step in the most widely distributed bacterial pathway for the initiation of phospholipid formation. The enzyme is membrane-bound.
