nickel incorporation protein HypB; HypB is one of numerous accessory proteins required for the maturation of nickel-dependent hydrogenases, like carbon monoxide dehydrogenase or urease. HypB is a GTP-binding protein and has GTP hyrolase activity. It forms homodimer and is capable of binding two nickel ions and two zinc ions. The active site is located on the dimer interface. Energy from hydrolysis of GTP is used to insert nickels into hydrogenases.

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.

urease accessory protein UreG; UreG is one of the four accessory proteins of urease. Urease is an enzyme which catalyzes the decomposition of urea to form ammonia and carbon dioxide. Bacterial urease is a trimer of three subunits which are encoded by genes ureA, ureB, and ureC. Up to four accessory proteins (ureD, ureE, ureF, and ureG) are required for urease catalytical function. UreG may play an important role in nickel incorporation of the urease metallocenter. UreG is a member of the Fer4_NifH superfamily which contains an ATP-binding domain. Proteins in this superfamily use the energy from hydrolysis of NTP to transfer electron or ion.

Circularly permuted YqeH GTPase; YqeH is an essential GTP-binding protein. Depletion of YqeH induces an excess initiation of DNA replication, suggesting that it negatively controls initiation of chromosome replication. The YqeH subfamily is common in eukaryotes and sporadically present in bacteria with probable acquisition by plants from chloroplasts. Proteins of the YqeH family contain all sequence motifs typical of the vast class of P-loop-containing GTPases, but show a circular permutation, with a G4-G1-G3 pattern of motifs as opposed to the regular G1-G3-G4 pattern seen in most GTPases.

Ribosomal interacting GTPase YjeQ/EngC, a circularly permuted subfamily of the Ras GTPases; YjeQ (YloQ in Bacillus subtilis) is a ribosomal small subunit-dependent GTPase; hence also known as RsgA. YjeQ is a late-stage ribosomal biogenesis factor involved in the 30S subunit maturation, and it represents a protein family whose members are broadly conserved in bacteria and have been shown to be essential to the growth of E. coli and B. subtilis. Proteins of the YjeQ family contain all sequence motifs typical of the vast class of P-loop-containing GTPases, but show a circular permutation, with a G4-G1-G3 pattern of motifs as opposed to the regular G1-G3-G4 pattern seen in most GTPases. All YjeQ family proteins display a unique domain architecture, which includes an N-terminal OB-fold RNA-binding domain, the central permuted GTPase domain, and a zinc knuckle-like C-terminal cysteine domain.

(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.
