Comments

| FUNCTION | Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine. |
| CATALYTIC ACTIVITY | Reaction=L-aspartate + H(+) = beta-alanine + CO2; Xref=Rhea:RHEA:19497, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:29991, ChEBI:CHEBI:57966; EC=4.1.1.11; |
| COFACTOR | Name=pyruvate; Xref=ChEBI:CHEBI:15361; Note=Binds 1 pyruvoyl group covalently per subunit.; |
| PATHWAY | Cofactor biosynthesis; (R)-pantothenate biosynthesis; beta- alanine from L-aspartate: step 1/1. |
| SUBUNIT | Heterooctamer of four alpha and four beta subunits. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| PTM | 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. |
| SIMILARITY | Belongs to the PanD family. |
