Tripartite ATP-independent periplasmic (TRAP) transporter large permease subunit is the membrane component of a TRAP tranporter, a substrate-binding protein (SBP)-dependent secondary transporter with similarity to C4-dicarboxylate TRAP transporter permease protein DctM
TRAP transporter, DctM subunit; The Tripartite ATP-independent Periplasmic Transporter (TRAP-T) Family (TC 2.A.56)- DctM subunit TRAP-T family permeases generally consist of three components, and these systems have so far been found in Gram-negative bacteria, Gram-postive bacteria and archaea. Only one member of the family has been both sequenced and functionally characterized. This system is the DctPQM system of Rhodobacter capsulatus (Forward et al., 1997). DctP is a periplasmic dicarboxylate (malate, fumarate, succinate) binding receptor that is biochemically well-characterized. DctQ is an integral cytoplasmic membrane protein with 4 putative transmembrane a-helical spanners (TMSs). DctM is a second integral cytoplasmic membrane protein with 12 putative TMSs. These proteins have been shown to be both necessary and sufficient for the proton motive force-dependent uptake of dicarboxylates into R. capsulatus.

Tripartite ATP-independent periplasmic transporter, DctM component; This family contains a diverse range of predicted transporter proteins. Including the DctM subunit of the bacterial and archaeal TRAP C4-dicarboxylate transport (Dct) system permease. In general, C4-dicarboxylate transport systems allow C4-dicarboxylates like succinate, fumarate, and malate to be taken up. TRAP C4-dicarboxylate carriers are secondary carriers that use an electrochemical H+ gradient as the driving force for transport. DctM is an integral membrane protein that is one of the constituents of TRAP carriers. Note that many family members are hypothetical proteins.

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.
