CC   -!- FUNCTION: Catalyzes a late step in pyrimidine degradation. Converts N-
CC       carbamoyl-beta-alanine (3-ureidopropanoate) into beta-alanine, ammonia
CC       and carbon dioxide. Likewise, converts N-carbamoyl-beta-
CC       aminoisobutyrate (3-ureidoisobutyrate) into beta-aminoisobutyrate,
CC       ammonia and carbon dioxide. {ECO:0000250|UniProtKB:Q9UBR1}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3-(carbamoylamino)propanoate + 2 H(+) + H2O = beta-alanine +
CC         CO2 + NH4(+); Xref=Rhea:RHEA:11184, ChEBI:CHEBI:11892,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:28938, ChEBI:CHEBI:57966; EC=3.5.1.6;
CC         Evidence={ECO:0000250|UniProtKB:Q9UBR1};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3-(carbamoylamino)-2-methylpropanoate + 2 H(+) + H2O = (R)-3-
CC         amino-2-methylpropanoate + CO2 + NH4(+); Xref=Rhea:RHEA:37339,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526,
CC         ChEBI:CHEBI:28938, ChEBI:CHEBI:57731, ChEBI:CHEBI:74414; EC=3.5.1.6;
CC         Evidence={ECO:0000250|UniProtKB:Q9UBR1};
CC   -!- PATHWAY: Amino-acid biosynthesis; beta-alanine biosynthesis.
CC       {ECO:0000250|UniProtKB:Q9UBR1}.
CC   -!- SUBUNIT: Homodimer, homotetramer, homooctamer; can also form higher
CC       homooligomers. {ECO:0000250|UniProtKB:Q9UBR1}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the carbon-nitrogen hydrolase superfamily. BUP
CC       family. {ECO:0000305}.
