riboflavin-specific deaminase C-terminal domain; Eubacterial riboflavin-specific deaminases have a zinc-binding domain recognized by the dCMP_cyt_deam model toward the N-terminus and this domain toward the C-terminus. Yeast HTP reductase, a riboflavin-biosynthetic enzyme, and several archaeal proteins believed related to riboflavin biosynthesis consist only of this domain and lack the dCMP_cyt_deam domain.

RibD C-terminal domain; The function of this domain is not known, but it is thought to be involved in riboflavin biosynthesis. This domain is found in the C terminus of RibD/RibG, in combination with pfam00383, as well as in isolation in some archaebacterial proteins. This family appears to be related to pfam00186.

riboflavin biosynthesis protein RibD; This model describes the ribD protein as found in Escherichia coli. The N-terminal domain includes the conserved zinc-binding site region captured in the model dCMP_cyt_deam and shared by proteins such as cytosine deaminase, mammalian apolipoprotein B mRNA editing protein, blasticidin-S deaminase, and Bacillus subtilis competence protein comEB. The C-terminal domain is homologous to the full length of yeast HTP reductase, a protein required for riboflavin biosynthesis. A number of archaeal proteins believed related to riboflavin biosynthesis contain only this C-terminal domain and are not found as full-length matches to this model.

2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine 1'-reductase, archaeal; This model represents a specific reductase of riboflavin biosynthesis in the Archaea, diaminohydroxyphosphoribosylaminopyrimidine reductase. It should not be confused with bacterial 5-amino-6-(5-phosphoribosylamino)uracil reductase. The intermediate 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine in riboflavin biosynthesis is reduced first, and then deaminated, in both Archaea and Fungi, opposite the order in Bacteria. The subsequent deaminase is not presently known and is not closely homologous to the deaminase domain (3.5.4.26) fused to the reductase domain (1.1.1.193) similar to this protein but found in most bacteria.

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.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,

Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(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)
