Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage

Chains	Enzyme Name	Description	Catalytic Residues
A	glycerol-3-phosphate O-acyltransferase M-CSA #783	Glycerol-3-phosphate (1)-acyltransferase (G3PAT) catalyses the attachment of an acyl group from either acyl-carrier proteins (acyl-ACPs) or acyl-CoAs onto the C1 hydroxyl group of glycerol-3-phosphate to give 1-acylglycerol-3-phosphate. Different G3PAT enzymes have different substrate specificities, with some preferring to add the unsaturated fatty acid oleate and others using both oleate and the saturated fatty acid palmitate. The different substrate specificities within this family has been implicated in the sensitivity of plants to chilling temperatures.
