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_03209}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phospho-L-serine + H(+) = a 1,2-
CC diacyl-sn-glycero-3-phosphoethanolamine + CO2; Xref=Rhea:RHEA:20828,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57262,
CC ChEBI:CHEBI:64612; EC=4.1.1.65; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_03209};
CC -!- COFACTOR:
CC Name=pyruvate; Xref=ChEBI:CHEBI:15361;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03209};
CC Note=Binds 1 pyruvoyl group covalently per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_03209};
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_03209}.
CC -!- SUBUNIT: Heterodimer of a large membrane-associated beta subunit and a
CC small pyruvoyl-containing alpha subunit. Interacts with pstB2. This
CC interaction may be a means to structurally tether the donor membrane
CC (ER) harboring PstB2 to acceptor membranes (Golgi/endosomes) harboring
CC PSD2 during PtdSer transport to the site of PtdEtn synthesis.
CC {ECO:0000256|HAMAP-Rule:MF_03209}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000256|HAMAP-
CC Rule:MF_03209}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_03209}; Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_03209}.
CC Endosome membrane {ECO:0000256|HAMAP-Rule:MF_03209}; Peripheral
CC membrane protein {ECO:0000256|HAMAP-Rule:MF_03209}; Cytoplasmic side
CC {ECO:0000256|HAMAP-Rule:MF_03209}.
CC -!- DOMAIN: The C2 domains have an essential, but non-catalytic function.
CC They may facilitate interaction with PstB2 and are required for lipid
CC transport function. {ECO:0000256|HAMAP-Rule:MF_03209}.
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_03209}.
CC -!- SIMILARITY: Belongs to the phosphatidylserine decarboxylase family.
CC PSD-B subfamily. Eukaryotic type II sub-subfamily. {ECO:0000256|HAMAP-
CC Rule:MF_03209}.
