dethiobiotin synthetase; Dethiobiotin synthetase (DTBS) is the penultimate enzyme in the biotin biosynthesis pathway in Escherichia coli and other microorganisms. The enzyme catalyzes formation of the ureido ring of dethiobiotin from (7R,8S)-7,8-diaminononanoic acid (DAPA) and carbon dioxide. The enzyme utilizes carbon dioxide instead of hydrogen carbonate as substrate and is dependent on ATP and divalent metal ions as cofactors.

dethiobiotin synthase; Dethiobiotin synthase is involved in biotin biosynthesis and catalyses the reaction (CO2 + 7,8-diaminononanoate + ATP = dethiobiotin + phosphate + ADP). The enzyme binds ATP (see motif in first 12 residues of the SEED alignment) and requires magnesium as a co-factor. [Biosynthesis of cofactors, prosthetic groups, and carriers, Biotin]

CobQ/CobB/MinD/ParA nucleotide binding domain; This family consists of various cobyrinic acid a,c-diamide synthases. These include CbiA and CbiP from S.typhimurium, and CobQ from R. capsulatus. These amidases catalyze 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. The family also contains dethiobiotin synthetases as well as the plasmid partitioning proteins of the MinD/ParA family.

DRTGG domain; This presumed domain is about 120 amino acids in length. It is found associated with CBS domains pfam00571, as well as the CbiA domain pfam01656. The function of this domain is unknown. It is named the DRTGG domain after some of the most conserved residues. This domain may be very distantly related to a pair of CBS domains. There are no significant sequence similarities, but its length and association with CBS domains supports this idea (Bateman A, pers. obs.).

N-terminal domain of cobyrinic acid a,c-diamide synthase; Cobyrinic acid a,c-diamide synthase (CobB, CbiA). Biosynthesis of cobalamin (vitamin B12) requires more than two dozen different enzymes. CobB catalyzes the ATP-dependent amidation of the two carboxylate groups at positions a and c of cobyrinic acid, via the formation of a phosphorylated intermediate, using glutamine or ammonia as the nitrogen source. CobB is comprised of two protein domains: the C-terminal glutaminase domain and the N-terminal ATP-binding domain. The glutaminase domain catalyzes the hydrolysis of glutamine to glutamate and ammonia. It belongs to the triad class of glutamine amidotransferases. This classification is based on the N-terminal domain which catalyzes the ultimate synthesis of the diamide product by using energy from the hydrolysis of ATP and ammonia transferred from the C-terminal domain.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(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.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.

(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
advanced search options)
