    A PF02492   cobW CobW/HypB/UreG, nucleotide-binding domain Domain 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 [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].

    A PF01656   CbiA CobQ/CobB/MinD/ParA nucleotide binding domain Domain This family consists of various cobyrinic acid a,c-diamide synthases. These include CbiA Swiss:P29946 and CbiP Swiss:Q05597 from S.typhimurium [4], and CobQ Swiss:Q52686 from R. capsulatus [3]. These amidases catalyse amidations to various side chains of hydrogenobyrinic acid or cobyrinic acid a,c-diamide in the biosynthesis of cobalamin (vitamin B12) from uroporphyrinogen III. Vitamin B12 is an important cofactor and an essential nutrient for many plants and animals and is primarily produced by bacteria [4]. The family also contains dethiobiotin synthetases as well as the plasmid partitioning proteins of the MinD/ParA family [6]. Source: Pfam
