>TIGR01792 urease_alph urease, alpha subunit; InterPro: IPR005848 Urease (urea amidohydrolase, 3.5.1.5 from EC) catalyses the hydrolysis of urea to form ammonia and carbamate. The subunit composition of urease from different sources varies , but each holoenzyme consists of four structural domains : three structural domains and a nickel-binding catalytic domain common to amidohydrolases . Urease is unique among nickel metalloenzymes in that it catalyses a hydrolysis rather than a redox reaction. In Helicobacter pylori, the gamma and beta domains are fused and called the alpha subunit (IPR008223 from INTERPRO). The catalytic subunit (called beta or B) has the same organization as the Klebsiella alpha subunit. Jack bean (Canavalia ensiformis) urease has a fused gamma-beta-alpha organization (IPR008221 from INTERPRO). This entry describes the urease alpha subunit UreC (designated beta or B chain, UreB in Helicobacter species). Urease (3.5.1.5 from EC) belongs to MEROPS peptidase family M38 (clan MJ). ; GO: 0009039 urease activity, 0016151 nickel ion binding, 0006807 nitrogen compound metabolic process.
