General annotation (Comments)

Function

May protect brucellae during their passage through the stomach. The major route of infection in human brucellosis is oral. Ref.1

Catalytic activity

Urea + H2O = CO2 + 2 NH3. HAMAP MF_01953

Cofactor

Binds 2 nickel ions per subunit By similarity. HAMAP MF_01953

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. HAMAP MF_01953

Subcellular location

Cytoplasm By similarity HAMAP MF_01953.

Post-translational modification

Carbamylation allows a single lysine to coordinate two nickel ions By similarity. HAMAP MF_01953

Disruption phenotype

Disruption of the ure1 gene cluster via a large in-frame deletion in this gene abrogates urease activity. Ref.1

Sequence similarities

Belongs to the urease family.

Contains 1 urease domain.
