C4-dicarboxylate transporters of the Tellurite-resistance/Dicarboxylate Transporter (TDT) family; This subfamily contains bacterial C4-dicarboxylate transporters, which is part of the Tellurite-resistance/Dicarboxylate Transporter (TDT) family. It includes Tellurite resistance protein tehA; the tehA gene encodes an integral membrane protein that has been shown to have efflux activity of quaternary ammonium compounds. TehA protein of Escherichia coli functions as a tellurite-resistance uptake permease.

Voltage-dependent anion channel; This family of transporters has ten alpha helical transmembrane segments. The structure of a bacterial homolog of SLAC1 shows it to have a trimeric arrangement. The pore is composed of five helices with a conserved Phe residue involved in gating. One homolog, Mae1 from the yeast Schizosaccharomyces pombe, functions as a malate uptake transporter; another, Ssu1 from Saccharomyces cerevisiae and other fungi including Aspergillus fumigatus, is characterized as a sulfite efflux pump; and TehA from Escherichia coli is identified as a tellurite resistance protein by virtue of its association in the tehA/tehB operon. In plants, this family is found in the stomatal guard cells functioning as an anion-transporting pore. Many homologs are incorrectly annotated as tellurite resistance or dicarboxylate transporter (TDT) proteins.

The Tellurite-resistance/Dicarboxylate Transporter (TDT) family includes TehA proteins; The Tellurite-resistance/Dicarboxylate Transporter (TDT) family includes members from all three kingdoms, but only three members of the family have been functionally characterized: the TehA protein of E. coli functioning as a tellurite-resistance uptake permease, the Mae1 protein of S. pombe functioning in the uptake of malate and other dicarboxylates, and the sulfite efflux pump (SSU1) of Saccharomyces cerevisiae. In plants, the plasma membrane protein SLAC1 (Slow Anion Channel-Associated 1), which is preferentially expressed in guard cells, encodes a distant homolog of fungal and bacterial dicarboxylate/malic acid transport proteins. SLAC1 is essential in mediating stomatal responses to physiological and stress stimuli. Members of the TDT family exhibit 10 putative transmembrane a-helical spanners (TMSs).

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,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
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
multi-domain models that were computationally detected and are likely to contain multiple single domains
