Secondary Accession Numbers Not Available
Name Phosphatidylserine synthase 1
Description Not Available
Synonyms
  1. PSS-1
  2. PtdSer synthase 1
  3. Serine-exchange enzyme I
Gene Name PTDSS1
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatidylserine biosynthetic process
Specific Function Catalyzes a base-exchange reaction in which the polar head group of phosphatidylethanolamine (PE) or phosphatidylcholine (PC) is replaced by L-serine. In membranes, PTDSS1 catalyzes mainly the conversion of phosphatidylcholine. Also converts, in vitro and to a lesser extent, phosphatidylethanolamine.
