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_01955};
CC   -!- PATHWAY: Nitrogen metabolism; urea degradation; CO(2) and NH(3) from
CC       urea (urease route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_01955}.
CC   -!- SUBUNIT: Heterohexamer of 3 UreA (alpha) and 3 UreB (beta) subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_01955}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01955}.
CC   -!- SIMILARITY: In the N-terminal section; belongs to the urease gamma
CC       subunit family. {ECO:0000255|HAMAP-Rule:MF_01955}.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the urease beta
CC       subunit family. {ECO:0000255|HAMAP-Rule:MF_01955}.
CC   -!- CAUTION: The orthologous protein is known as the gamma/beta subunit
CC       (UreAB) in most other bacteria. {ECO:0000305}.
