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

Function

• catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine is replaced by L-serine
• inhibited by excess phosphatidylserine, but not by phosphatidylcholine or phosphatidylethanolamine
• phosphatidylserine biosynthesis

Structure

belongs to the phosphatidyl serine synthase family

Compartment

membrane

More general terms

• transmembrane 8 protein
• phosphotransferase
