cobalamin synthesis protein CobW; The function of this protein family is unknown. The amino acid sequence of YjiA protein in E. coli contains several conserved motifs that characterizes it as a P-loop GTPase. YijA gene is among the genes significantly induced in response to DNA-damage caused by mitomycin. YijA gene is a homologue of the CobW gene which encodes the cobalamin synthesis protein/P47K.

CobW/HypB/UreG, nucleotide-binding 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. HypB has GTPase activity and is a guanine nucleotide binding protein. 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. UreG is required for functional incorporation of the urease nickel metallocenter. GTP hydrolysis may required by these proteins for nickel incorporation into other nickel proteins. This family of domains also contains P47K, a Pseudomonas chlororaphis protein needed for nitrile hydratase expression, and the cobW gene product, which may be involved in cobalamin biosynthesis in Pseudomonas denitrificans.

cobalamin biosynthesis protein CobW; The family of proteins identified by this model is generally found proximal to the trimeric cobaltochelatase subunit CobN which is essential for vitamin B12 (cobalamin) biosynthesis. The protein contains an P-loop nucleotide-binding loop in the N-terminal domain and a histidine-rich region in the C-terminal portion suggesting a role in metal binding, possibly as an intermediary between the cobalt transport and chelation systems. A broader CobW family is delineated by two Pfam models which identify the N- and C-terminal domains (pfam02492 and pfam07683).

Cobalamin synthesis protein cobW C-terminal domain; This is a large and diverse family of putative metal chaperones that can be separated into up to 15 subgroups. In addition to known roles in cobalamin biosynthesis 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.

DEXS-box helicase domain of RecD and similar proteins; RecD is a member of the RecBCD (EC 3.1.11.5, Exonuclease V) complex. It is the alpha chain of the complex and functions as a 3'-5' helicase. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA. RecD is a member of the DEAD-like helicase superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

ATP-binding cassette domain of the drug resistance transporter and related proteins, subfamily A; This family of ATP-binding proteins belongs to a multi-subunit transporter involved in drug resistance (BcrA and DrrA), nodulation, lipid transport, and lantibiotic immunity. In bacteria and archaea, these transporters usually include an ATP-binding protein and one or two integral membrane proteins. Eukaryotic systems of the ABCA subfamily display ABC domains that are quite similar to this family. The ATP-binding domain shows the highest similarity between all members of the ABC transporter family. ABC transporters are a subset of nucleotide hydrolases that contain a signature motif, Q-loop, and H-loop/switch region, in addition to, the Walker A motif/P-loop and Walker B motif commonly found in a number of ATP- and GTP-binding and hydrolyzing proteins.
