Protein attributes

Sequence length	208 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Facilitates the functional incorporation of the urease nickel metallocenter. This process requires GTP hydrolysis, probably effectuated by ureG By similarity. 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
Subunit structure	Homodimer. UreD, ureF and ureG form a complex that acts as a GTP-hydrolysis-dependent molecular chaperone, activating the urease apoprotein by helping to assemble the nickel containing metallocenter of ureC. The ureE protein probably delivers the nickel By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the ureG family.
