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: May form a heterohexamer of 3 UreC (alpha) and 3 UreAB
CC       (gamma/beta) subunits. May also form a heterotrimer of UreA (gamma),
CC       UreB (beta) and UreC (alpha) subunits. Three heterotrimers associate to
CC       form the active enzyme. {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}.
