Subsystem: Urease subunits
This subsystem's description is:
Urease is a nickel metallo enzyme that catalyzes the degredation of urea to ammonia and carbamine acid. The latter compound decomposes spontaneously to form a second molecule of ammonia and carbon dioxide.
The enzyme consists of three subunits, alpha, beta and gamma. This heterotrimer forms multimers, mainly trimers.
UreA and UreB = needed for the association of the urease heterotrimer UreABC
UreC = catalytic domain containing an active site with a Ni2+ center complexed by a carbamylated lysine
UreE = metallochaperone assisting the insertion of a Ni2+ ion in the active site of urease
UreF = modulates activation of urease by eliminating Ni2+ irons from the non-carbamylated protein
UreG = GTP hydrolase needed for the assembly of the Ni2+ metallocenter of urease
UreD = needed for the assembly of the Ni2+ metallocenter
Nomenclature for urease subunits in Helicobacter might differ from this SS
