phosphatidylserine synthase; serine-exchange enzyme 1; CDP diacylglycerol serine O-phosphatidyltransferase (PTDSS1)

Function

• catalyzes a base-exchange reaction in which the polar head group of phosphatidylcholine is replaced by L-serine
• phosphatidylserine biosynthesis
• may provide a precursor for the biosynthesis of phosphatidylethanolamine
• phosphatidylserine can be decarboxylated to phosphatidylethanolamine

Structure

belongs to the phosphatidyl serine synthase family

Compartment

membrane

More general terms

• phosphotransferase
• membrane protein

Additional terms

• phosphatidylserine synthase 2 (Ptdser synthase 2, PSS-2, serine-exchange enzyme 2, PTDSS2, PSS2)
