CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 H(+) + H2O + urea = CO2 + 2 NH4(+); Xref=Rhea:RHEA:20557,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16199,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:28938; EC=3.5.1.5;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01953};
CC -!- COFACTOR:
CC Name=Ni cation; Xref=ChEBI:CHEBI:25516;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01953};
CC Note=Binds 2 nickel ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01953};
CC -!- PATHWAY: Nitrogen metabolism; urea degradation; CO(2) and NH(3) from
CC urea (urease route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_01953}.
CC -!- SUBUNIT: Heterohexamer of 3 UreA (alpha) and 3 UreB (beta) subunits.
CC {ECO:0000255|HAMAP-Rule:MF_01953}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01953}.
CC -!- PTM: Carboxylation allows a single lysine to coordinate two nickel
CC ions. {ECO:0000255|HAMAP-Rule:MF_01953}.
CC -!- SIMILARITY: Belongs to the metallo-dependent hydrolases superfamily.
CC Urease alpha subunit family. {ECO:0000255|HAMAP-Rule:MF_01953}.
CC -!- CAUTION: The orthologous protein is known as the alpha subunit (UreC)
CC in most other bacteria. {ECO:0000305}.
