CC -!- FUNCTION: Catalyzes the formation of phosphatidylethanolamine (PtdEtn)
CC from phosphatidylserine (PtdSer). Plays a central role in phospholipid
CC metabolism and in the interorganelle trafficking of phosphatidylserine.
CC {ECO:0000256|HAMAP-Rule:MF_03208}.

CC Evidence={ECO:0000256|HAMAP-Rule:MF_03208};
CC Note=Binds 1 pyruvoyl group covalently per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_03208};
CC -!- PATHWAY: Lipid metabolism. {ECO:0000256|ARBA:ARBA00005189}.
CC -!- PATHWAY: Phospholipid metabolism; phosphatidylethanolamine
CC biosynthesis; phosphatidylethanolamine from CDP-diacylglycerol: step
CC 2/2. {ECO:0000256|HAMAP-Rule:MF_03208}.
CC -!- SUBUNIT: Heterodimer of a large membrane-associated beta subunit and a
CC small pyruvoyl-containing alpha subunit. {ECO:0000256|HAMAP-
CC Rule:MF_03208}.
CC -!- SUBCELLULAR LOCATION: [Phosphatidylserine decarboxylase 1 alpha chain]:
CC Mitochondrion inner membrane {ECO:0000256|HAMAP-Rule:MF_03208};
CC Peripheral membrane protein {ECO:0000256|HAMAP-Rule:MF_03208};
CC Intermembrane side {ECO:0000256|HAMAP-Rule:MF_03208}. Note=Anchored to
CC the mitochondrial inner membrane through its interaction with the
CC integral membrane beta chain. {ECO:0000256|HAMAP-Rule:MF_03208}.
CC -!- SUBCELLULAR LOCATION: [Phosphatidylserine decarboxylase 1 beta chain]:
CC Mitochondrion inner membrane {ECO:0000256|HAMAP-Rule:MF_03208}; Single-
CC pass membrane protein {ECO:0000256|HAMAP-Rule:MF_03208}; Intermembrane
CC side {ECO:0000256|HAMAP-Rule:MF_03208}.
CC -!- PTM: Is synthesized initially as an inactive proenzyme. Formation of
CC the active enzyme involves a self-maturation process in which the
CC active site pyruvoyl group is generated from an internal serine residue
CC via an autocatalytic post-translational modification. Two non-identical
CC subunits are generated from the proenzyme in this reaction, and the
CC pyruvate is formed at the N-terminus of the alpha chain, which is
CC derived from the carboxyl end of the proenzyme. The autoendoproteolytic
CC cleavage occurs by a canonical serine protease mechanism, in which the
CC side chain hydroxyl group of the serine supplies its oxygen atom to
CC form the C-terminus of the beta chain, while the remainder of the
CC serine residue undergoes an oxidative deamination to produce ammonia
CC and the pyruvoyl prosthetic group on the alpha chain. During this
CC reaction, the Ser that is part of the protease active site of the
CC proenzyme becomes the pyruvoyl prosthetic group, which constitutes an
CC essential element of the active site of the mature decarboxylase.
CC {ECO:0000256|HAMAP-Rule:MF_03208}.
CC -!- SIMILARITY: Belongs to the phosphatidylserine decarboxylase family.
CC PSD-B subfamily. Eukaryotic type I sub-subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_03208}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
