In enzymology, a glycerol-3-phosphate O-acyltransferase (EC 2.3.1.15) is an enzyme that catalyzes the chemical reaction
- acyl-CoA + sn-glycerol 3-phosphate 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 1IUQ and 1K30. Currently 4 different proteins are assigned to this reaction, GPAT1, GPAT2, GPAT3 and GPAT4. GPAT1 and 2 are considered mitochondrial proteins.[2][3]
