IUBMB Enzyme Nomenclature

EC 2.3.1.274

Accepted name: phosphate acyltransferase

Reaction: an acyl-[acyl-carrier protein] + phosphate = an acyl phosphate + an [acyl-carrier protein]

Other name(s): plsX (gene name); acyl-ACP phosphotransacylase; acyl-[acyl-carrier-protein]—phosphate acyltransferase; phosphate-acyl-ACP acyltransferase

Systematic name: an acyl-[acyl-carrier protein]:phosphate acyltransferase

Comments: The enzyme, found in bacteria, catalyses the synthesis of fatty acyl-phosphate from acyl-[acyl-carrier protein], a step in the most widely distributed bacterial pathway for the initiation of phospholipid formation. While the activity is modestly enhanced by Mg2+, the enzyme does not require a divalent cation.
