Secondary Accession Numbers
  • 8475
  • HMDBP05127
Name Phosphatidylserine synthase 2
Synonyms
  1. PSS-2
  2. PtdSer synthase 2
  3. Serine-exchange enzyme II
Gene Name PTDSS2
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. PTDSS2 is specific for phosphatatidylethanolamine and does not act on phosphatidylcholine.
Pathways
  • Glycerophospholipid metabolism
  • phosphatidylserine biosynthesis
  • Phospholipid Biosynthesis
Reactions
L-1-phosphatidylethanolamine + L-Serine → L-1-phosphatidylserine + Ethanolamine details
