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_01954};
CC   -!- PATHWAY: Nitrogen metabolism; urea degradation; CO(2) and NH(3) from
CC       urea (urease route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_01954}.
