Ure proteins are involved in urease activation by the transfer of Ni into the protein[1]. UreE - see Molecular Playground/UreE. UreF - modulates the activation process of urease by eliminating the binding of Ni irons to noncarbamylated protein[2]. UreG - modulates the activation process of urease in plants [3]. UreH - forms in combination with UreF and UreG a pre-activation complex which activates urease[4]. UreI - probably facilitates nickel incorporation. Structural highlights The [5]. Water molecule is shown as red sphere.
