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.

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.

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).

Tetrahymena thermophila shulin, human uncharacterized protein C20orf194, and similar proteins; This family contains Tetrahymena thermophila shulin, human uncharacterized protein C20orf194, and similar proteins. Shulin is a negative regulator of the ciliary outer dynein arm (ODA). It binds newly synthesized ODAs, locks the dynein motors together by shutting off motor activity, and facilitates the delivery of ODAs from the cytoplasm to their final position in the cilia. ODAs, together with inner dynein arms (IDAs), are arrayed along a microtubule-based structure called the axoneme and drive the movement of cilia. Human C20orf194 interacts with the small GTPase Arf-like 3 (ARL3) and may act as its effector. The rs6051702 single nucleotide polymorphism (SNP) within the C20orf194 gene is associated with inosine triphosphatase (ITPA) functional gene polymorphisms that were found to influence RBV-induced hemoglobin (Hb)-decline during treatment of chronic hepatitis C patients with pegylated interferon (PEG-IFN) plus ribavirin (RBV).

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.

(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
