CC -!- FUNCTION: Catalyzes the pyruvoyl-dependent decarboxylation of aspartate
CC to produce beta-alanine. {ECO:0000255|HAMAP-Rule:MF_00446}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-aspartate = beta-alanine + CO2; Xref=Rhea:RHEA:19497,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:29991,
CC ChEBI:CHEBI:57966; EC=4.1.1.11; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00446};
CC -!- COFACTOR:
CC Name=pyruvate; Xref=ChEBI:CHEBI:15361;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00446};
CC Note=Binds 1 pyruvoyl group covalently per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00446};
CC -!- PATHWAY: Cofactor biosynthesis; (R)-pantothenate biosynthesis; beta-
CC alanine from L-aspartate: step 1/1. {ECO:0000255|HAMAP-Rule:MF_00446}.
CC -!- SUBUNIT: Heterooctamer of four alpha and four beta subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00446}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00446}.
CC -!- PTM: Is synthesized initially as an inactive proenzyme, which is
CC activated by self-cleavage at a specific serine bond to produce a beta-
CC subunit with a hydroxyl group at its C-terminus and an alpha-subunit
CC with a pyruvoyl group at its N-terminus. {ECO:0000255|HAMAP-
CC Rule:MF_00446}.
CC -!- SIMILARITY: Belongs to the PanD family. {ECO:0000255|HAMAP-
CC Rule:MF_00446}.
