General rule information [?]

Accession PRU00700
Dates 27-MAR-2008 (Created)

Data class Domain;
Predictors PROSITE; PS51368; UREASE_3
Name Urease domain
Function Urease (EC 3.5.1.5) is a nickel-binding enzyme that catalyzes the hydrolysis of urea to carbon dioxide and ammonia. The urease domain forms an (alpha beta)(8) barrel structure that binds two nickel ions and with a histidine that is catalytically involved.
Scope(s) Eukaryota
Bacteria
Archaea
Example(s) Q5KCQ6 (UREA_CRYNE);
