beta-ketoadipate pathway transcriptional regulators, PcaR/PcaU/PobR family; Member of this family are IclR-type transcriptional regulators with similar DNA binding sites, able to bind at least three different metabolites related to protocatechuate metabolism. Beta-ketoadipate is the inducer for PcaR, p-hydroxybenzoate for PobR, and protocatechuate for PcaU. [Regulatory functions, DNA interactions]

Bacterial transcriptional regulator; This family of bacterial transcriptional regulators includes the glycerol operon regulatory protein and acetate operon repressor both of which are members of the iclR family. These proteins have a Helix-Turn-Helix motif at the N-terminus. However this family covers the C-terminal region that binds to regulatory substrates including Glyoxylate, allantoin/ate, indole, aromatic hydrocarbons, sugar acids, succinic semialdehyde, benzoate derivatives, ascorbic acid, glycerol-3-phosphate, glyceraldehyde-3-phosphate and pyruvate (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

MarR family; The Mar proteins are involved in the multiple antibiotic resistance, a non-specific resistance system. The expression of the mar operon is controlled by a repressor, MarR. A large number of compounds induce transcription of the mar operon. This is thought to be due to the compound binding to MarR, and the resulting complex stops MarR binding to the DNA. With the MarR repression lost, transcription of the operon proceeds. The structure of MarR is known and shows MarR as a dimer with each subunit containing a winged-helix DNA binding motif.

Penicillinase repressor; The penicillinase repressor negatively regulates expression of the penicillinase gene. The N-terminal region of this protein is involved in operator recognition, while the C-terminal is responsible for dimerization of the protein.

Iron-dependent Transcriptional regulator; Several proteins in this family form iron-sulfur clusters enabling iron dependent DNA transcription regulation. The iron binding is mediated by three conserved cysteine residues. Members of this family can also bind O-acetyl-L-serine, [Fe-S] and nitric oxide (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).

Rrf2 family protein; This model represents a superfamily of probable transcriptional regulators. One member, RRF2 of Desulfovibrio vulgaris is an apparent regulatory protein experimentally (MEDLINE:97293189). The N-terminal region appears related to the DNA-binding biotin repressor region of the BirA bifunctional according to results after three rounds of PSI-BLAST with a fairly high stringency.

of the residues that compose this conserved feature have been mapped to the query sequence.
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.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

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)
the domain superfamily to which the specific and non-specific hits belong
