Protein attributes

Sequence length	393 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Converts N-carbamyl-beta-aminoisobutyric acid and N-carbamyl-beta-alanine to, respectively, beta-aminoisobutyric acid and beta-alanine, ammonia and carbon dioxide.
Catalytic activity	N-carbamoyl-beta-alanine + H2O = beta-alanine + CO2 + NH3.
Cofactor	Binds 2 zinc ions per subunit By similarity.
Enzyme regulation	Allosteric enzyme with positive cooperativity toward the substrate N-carbamoyl-beta-alanine.
Pathway	Amino-acid biosynthesis; beta-alanine biosynthesis.
Subunit structure	In the absence of ligands, the enzyme exists as a stable homohexamer, although this is not the most active form of the enzyme. This native hexamer dissociates to an inactive trimer in response to the product, beta-alanine, or associates to the more active homododecamer in response to the substrate.
Subcellular location	Cytoplasm.
Post-translational modification	The N-terminus is blocked.
Sequence similarities	Belongs to the CN hydrolase family. BUP subfamily. Contains 1 CN hydrolase domain.
