General annotation (Comments)

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

Heterohexamer of 3 ureA (alpha) and 3 ureB (beta) subunits 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

Sequence similarities

Belongs to the urease family.

Contains 1 urease domain.

Caution

The orthologous protein is known as the alpha subunit (ureC) in most other bacteria.
