In enzymology, a 1-alkyl-2-acetylglycerophosphocholine esterase (EC 184.108.40.206) is an enzyme that catalyzes the chemical reaction1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H2O
Thus, the two substrates of this enzyme are 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine and H2O, whereas its two products are 1-alkyl-sn-glycero-3-phosphocholine and acetate.
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine acetohydrolase. Other names in common use include 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine acetylhydrolase, and alkylacetyl-GPC:acetylhydrolase. This enzyme participates in ether lipid metabolism.
As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1BWP, 1BWQ, 1BWR, 1ES9, 1FXW, 1VYH, and 1WAB.
