Comments [?]

Function Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine.
Catalytic activity RHEA:19497: H(+) + L-aspartate = beta-alanine + CO2
EC 4.1.1.11
Cofactor pyruvate
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.
