glycerone-phosphate O-acyltransferase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: acyl-CoA + glycerone phosphate = 1-acylglycerone 3-phosphate + CoA. [EC:2.3.1.42, RHEA:17657]
Glycerone-phosphate O-acyltransferase activity catalyzes the transfer of an acyl group from an acyl donor, such as acyl-CoA, to the hydroxyl group at the sn-1 position of glycerone phosphate. This reaction is the first committed step in the biosynthesis of triacylglycerols (TAGs) and phospholipids, which are essential components of cell membranes and energy storage. Glycerone phosphate O-acyltransferases are highly specific for their substrates, and different enzymes have different preferences for acyl donors and acceptors. For example, some enzymes prefer long-chain fatty acids, while others prefer short-chain fatty acids. The activity of glycerone phosphate O-acyltransferases is regulated by various factors, including substrate availability, enzyme phosphorylation, and the presence of specific inhibitors. This regulation ensures that the synthesis of TAGs and phospholipids is tightly controlled in response to cellular needs.'
