General annotation (Comments)

Function	Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine.
Catalytic activity	L-aspartate = beta-alanine + CO(2).
Cofactor	Pyruvoyl group.
Enzyme regulation	Inhibited by hydroxylamine, phenylhydrazine, sodium borohydride, D-cycloserine, hydrazine, semicarbazine and succinic dehydrazine. L-glutamate, succinate, oxaloacetate, L-serine, L-cysteic acid, beta-hydroxy-DL-asparate, and D-serine are competitive inhibitors By similarity.
Pathway	Cofactor biosynthesis; pantothenate biosynthesis; beta-alanine from L-aspartate: step 1/1.
Subunit structure	Heterooctamer of four alpha and four beta subunits.
Subcellular location	Cytoplasm.
Post-translational modification	Is synthesized initially as an inactive proenzyme, which is activated by self-cleavage at a specific serine bond to produce a beta-subunit with a hydroxyl group at its C-terminus and an alpha-subunit with a pyruvoyl group at its N-terminus.
Sequence similarities	Belongs to the panD family.
