General annotation (Comments)

Catalytic activity

Urea + H2O = CO2 + 2 NH3. HAMAP MF_01953

Cofactor

Binds 2 nickel ions per subunit By similarity.

Pathway

Nitrogen metabolism; urea degradation; CO(2) and NH(3) from urea (urease route): step 1/1. HAMAP MF_01953

Subunit structure

Heterotrimer of ureA (gamma), ureB (beta) and ureC (alpha) subunits. Three heterotrimers associate to form the active enzyme By similarity.

Subcellular location

Cytoplasm By similarity.

Post-translational modification

Carbamylation allows a single lysine to coordinate two nickel ions By similarity.

Sequence similarities

Belongs to the urease family.

Contains 1 urease domain.
