Ec Number:2.3.1.15
Cas Number:9029-96-3
Go Code:0004366

In enzymology, a glycerol-3-phosphate O-acyltransferase is an enzyme that catalyzes the chemical reaction

acyl-CoA + sn-glycerol 3-phosphate

\rightleftharpoons

CoA + 1-acyl-sn-glycerol 3-phosphate

Thus, the two substrates of this enzyme are acyl-CoA and sn-glycerol 3-phosphate, whereas its two products are CoA and 1-acyl-sn-glycerol 3-phosphate.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acyl-CoA:sn-glycerol-3-phosphate 1-O-acyltransferase. Other names in common use include alpha-glycerophosphate acyltransferase, 3-glycerophosphate acyltransferase, ACP:sn-glycerol-3-phosphate acyltransferase, glycerol 3-phosphate acyltransferase, glycerol phosphate acyltransferase, glycerol phosphate transacylase, glycerophosphate acyltransferase, glycerophosphate transacylase, sn-glycerol 3-phosphate acyltransferase, and sn-glycerol-3-phosphate acyltransferase. This enzyme participates in glycerolipid metabolism and glycerophospholipid metabolism. The later pathways in human is part of the WikiPathways[1] machine readable pathway collection.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and . Currently 4 different proteins are assigned to this reaction, GPAT1, GPAT2, GPAT3 and GPAT4. GPAT1 and 2 are considered mitochondrial proteins.[2] [3]
