Phosphatidylcholine synthase

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


 * CDP-diacylglycerol + choline $$\rightleftharpoons$$ CMP + phosphatidylcholine

Thus, the two substrates of this enzyme are CDP-diacylglycerol and choline, whereas its two products are CMP and phosphatidylcholine.

This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is CDP-diacylglycerol:choline O-phosphatidyltransferase. This enzyme is also called CDP-diglyceride-choline O-phosphatidyltransferase. This enzyme participates in glycerophospholipid metabolism.
