Protein attributes

Sequence length	128 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine By similarity. HAMAP-Rule MF_00446
Catalytic activity	L-aspartate = beta-alanine + CO2. HAMAP-Rule MF_00446
Cofactor	Pyruvoyl group By similarity.
Pathway	Cofactor biosynthesis; (R)-pantothenate biosynthesis; beta-alanine from L-aspartate: step 1/1. HAMAP-Rule MF_00446
Subunit structure	Heterooctamer of four alpha and four beta subunits By similarity.
Subcellular location	Cytoplasm By similarity.
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 By similarity. HAMAP-Rule MF_00446
Sequence similarities	Belongs to the PanD family.
