PF02492CobW/HypB/UreG, nucleotide-binding domain (cobW)CobW/HypB/UreG, nucleotide-binding domainThis domain is found in HypB, a hydrogenase expression / formation protein, and UreG a urease accessory protein. Both these proteins contain a P-loop nucleotide binding motif [2,3].

Both these proteins contain a P-loop nucleotide binding motif [2,3]. HypB has GTPase activity and is a guanine nucleotide binding protein [3]. It is not known whether UreG binds GTP or some other nucleotide. Both enzymes are involved in nickel binding. HypB can store nickel and is required for nickel dependent hydrogenase expression [1]. UreG is required for functional incorporation of the urease nickel metallocenter.[4] GTP hydrolysis may required by these proteins for nickel incorporation into other nickel proteins [1]. This family of domains also contains P47K (Swiss:P31521), a Pseudomonas chlororaphis protein needed for nitrile hydratase expression, and the cobW gene product (Swiss:P29937), which may be involved in cobalamin biosynthesis in Pseudomonas denitrificans [5].

In addition to known roles in cobalamin biosynthesis [1] and the activation of the Fe-type nitrile hydratase, this family is also known to be involved in the response to zinc limitation. The CobW subgroup involved in cobalamin synthesis represents only a small sub-fraction of the family [2].
