Function
function
Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine.
Catalytic activity
- L-aspartate + H+ = beta-alanine + CO2
Cofactor
Note: Binds 1 pyruvoyl group covalently per subunit.
Pathway
Cofactor biosynthesis; (R)-pantothenate biosynthesis; beta-alanine from L-aspartate: step 1/1.

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.
