PS_Dcarbxylase

PS_Dcarbxylase
PFAM accession number:PF02666
Interpro abstract (IPR003817): 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 [(PUBMED:8407984)]. Phosphatidylserine decarboxylases EC 4.1.1.65 is responsible for conversion of phosphatidylserine to phosphatidylethanolamine and plays a central role in the biosynthesis of aminophospholipids [(PUBMED:7890740)]. This family also includes L-tryptophan decarboxylase from the mushroom Psilocybe cubensis, which is required for the biosynthesis of the psychotropic agent psilocybin. This enzyme catalyses the first step in the biosynthetic pathway, converting L-tryptophan to tryptamine [(PUBMED:28763571)].
GO process:phospholipid biosynthetic process (GO:0008654)
GO function:phosphatidylserine decarboxylase activity (GO:0004609)
