Disulphide bond corrector protein DsbC; This entry represents the N-terminal domain of DsbD, a transmembrane electron transporter. DsbD binds to a DsbC dimer and selectively activates it using electrons from the cytoplasm. The N-terminal domain of DsbD (DsbDN) is capable of forming disulfides with oxidized DsbC, DsbE, or DsbG as well as with reduced DsbD.

DsbD gamma family; DsbD gamma is the C-terminal periplasmic domain of the bacterial protein DsbD. It contains a CXXC motif in a TRX fold and shuttles the reducing potential from the membrane domain (DsbD beta) to the N-terminal periplasmic domain (DsbD alpha). DsbD beta, a transmembrane domain comprising of eight helices, acquires its reducing potential from the cytoplasmic thioredoxin. DsbD alpha transfers the acquired reducing potential from DsbD gamma to target proteins such as the periplasmic protein disulphide isomerases, DsbC and DsbG. This flow of reducing potential from the cytoplasm through DsbD allows DsbC and DsbG to act as isomerases in the oxidizing environment of the bacterial periplasm. DsbD also transfers reducing potential from the cytoplasm to specific reductases in the periplasm which are involved in the maturation of cytochromes.

Cytochrome C biogenesis protein transmembrane region; This family consists of the transmembrane (i.e. non-catalytic) region of Cytochrome C biogenesis proteins also known as disulphide interchange proteins. These proteins posses a protein disulphide isomerase like domain that is not found within the aligned region of this family.

SoxW family; SoxW is a bacterial periplasmic TRX, containing a redox active CXXC motif, encoded by a genetic locus (sox operon) involved in thiosulfate oxidation. Sulfur bacteria oxidize sulfur compounds to provide reducing equivalents for carbon dioxide fixation during autotrophic growth and the respiratory electron transport chain. It is unclear what the role of SoxW is, since it has been found to be dispensable in the oxidation of thiosulfate to sulfate. SoxW is specifically kept in the reduced state by SoxV, which is essential in thiosulfate oxidation.

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

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.
