General Information
DescriptionPhosphatidylserine decarboxylase proenzyme (ec .
SpeciesHomo sapiens (NCBI taxonomy ID: 9606)
Domain Architecture (Details)
InterPro domains unassigned to SynO:
Phosphatidylserine decarboxylase plays a pivotal role in the synthesis of phospholipid by the mitochondria. The substrate phosphatidylserine is synthesized extramitochondrially and must be translocated to the mitochondria prior to decarboxylation . Phosphatidylserine decarboxylases is responsible for conversion of phosphatidylserine to phosphatidylethanolamine and plays a central role in the biosynthesis of aminophospholipids .
  IPR003817:Phosphatidylserine decarboxylase-related
Phosphatidylserine decarboxylase is synthesized as a single chain precursor. Generation of the pyruvoyl active site from a Ser is coupled to cleavage of a Gly-Ser bond between the larger (beta) and smaller (alpha chains). It is an integral membrane protein.
