Alanylphosphatidylglycerol synthase

In enzymology, an alanylphosphatidylglycerol synthase is an enzyme that catalyzes the chemical reaction


 * L-alanyl-tRNA + phosphatidylglycerol $$\rightleftharpoons$$ tRNA + 3-O-L-alanyl-1-O-phosphatidylglycerol

Thus, the two substrates of this enzyme are L-alanyl-tRNA and phosphatidylglycerol, whereas its two products are tRNA and 3-O-L-alanyl-1-O-phosphatidylglycerol.

This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is L-alanyl-tRNA:phosphatidylglycerol alanyltransferase. Other names in common use include O-alanylphosphatidylglycerol synthase, and alanyl phosphatidylglycerol synthetase.
