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:L-serine 3-sn-phosphatidyltransferase. Other names in common use include phosphatidylserine synthase, CDPdiglyceride-serine O-phosphatidyltransferase, PS synthase, cytidine 5'-diphospho-1,2-diacyl-sn-glycerol, (CDPdiglyceride):L-serine O-phosphatidyltransferase, phosphatidylserine synthetase, CDP-diacylglycerol-L-serine O-phosphatidyltransferase, cytidine diphosphoglyceride-serine O-phosphatidyltransferase, CDP-diglyceride-L-serine phosphatidyltransferase, CDP-diglyceride:serine phosphatidyltransferase, cytidine 5'-diphospho-1,2-diacyl-sn-glycerol:L-serine, O-phosphatidyltransferase, and CDP-diacylglycerol:L-serine 3-O-phosphatidyltransferase. This enzyme participates in glycine, serine and threonine metabolism and glycerophospholipid metabolism.
