UreB
Urease B (UreB) is one of the main H. pylori antigens. It is a subunit of enzyme urease, composed of A and B subunit that neutralizes the pH around the microorganism by decomposing urea into ammonia and carbon dioxide, thus enabling H. pylori to survive in the acidic gastric environment. Application of this antigen should elicit production of neutralizing antibodies thus inhibiting enzymatic activity of urease, which could lead to the eventual eradication of bacteria.
Additional Information
UreB is a member of the metallo-dependent hydrolases superfamily and requires a nickel (Ni) cation as a cofactor to perform its enzymatic activity. Each subunit of UreB associates with two nickel ions.
