CobW/HypB/UreG, nucleotide-binding domain
PF02492
Definition
This 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 [[cite:PMID:9209019],[cite:PMID:8423137]]. HypB has GTPase activity and is a guanine nucleotide binding protein PMID:8423137. 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 PMID:9140970. UreG is required for functional incorporation of the urease nickel metallocenter.PMID:1624427 GTP hydrolysis may required by these proteins for nickel incorporation into other nickel proteins PMID:9140970. This family of domains also contains P47K ([swissprot:P31521]), a Pseudomonas chlororaphis protein needed for nitrile hydratase expression, and the cobW gene product ([swissprot:P29937]), which may be involved in cobalamin biosynthesis in Pseudomonas denitrificans PMID:1655697.
