Function
Urease accessory protein (Ure) is a Ni-containing urea hydrolase involved in nitrogen recycling from arginine, ureide and purines. Ure proteins are involved in urease activation by the transfer of Ni into the protein[1].
- UreD - required for nickel incorporation [2].
- UreE - see Molecular Playground/UreE.
- UreF - modulates the activation process of urease by eliminating the binding of Ni irons to noncarbamylated protein[3].
- UreG - modulates the activation process of urease in plants [4].
- UreH - forms in combination with UreF and UreG a pre-activation complex which activates urease[5].
- UreI - probably facilitates nickel incorporation.
