In enzymology, an alkylglycerophosphate 2-O-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + 1-alkyl-sn-glycero-3-phosphate CoA + 1-alkyl-2-acetyl-sn-glycero-3-phosphate Thus, the two substrates of this enzyme are acetyl-CoA and 1-alkyl-sn-glycero-3-phosphate, whereas its two products are CoA and 1-alkyl-2-acetyl-sn-glycero-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 acetyl-CoA:1-alkyl-sn-glycero-3-phosphate 2-O-acetyltransferase. This enzyme is also called alkyllyso-GP:acetyl-CoA acetyltransferase. This enzyme participates in ether lipid metabolism. References EC 2.3.1 Enzymes of unknown structure
