Bacteria › Proteobacteria › Alphaproteobacteria › Rhizobiales › Brucellaceae › Brucella

Protein attributes

Sequence length	101 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Disruption of the ure1 gene cluster suggests that it protects 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_01954
Pathway	Nitrogen metabolism; urea degradation; CO(2) and NH(3) from urea (urease route): step 1/1. HAMAP MF_01954
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.
Sequence similarities	Belongs to the urease beta subunit family.
