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=L-aspartate + H(+) = 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; Evidence={ECO:0000255|HAMAP-
CC         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}.
