TRX domain, SSP411 protein family; members of this family are highly conserved proteins present in eukaryotes, bacteria and archaea, about 600-800 amino acids in length, which contain a TRX domain with a redox active CXXC motif. The human/rat protein, called SSP411, is specifically expressed in the testis in an age-dependent manner. The SSP411 mRNA is increased during spermiogenesis and is localized in round and elongated spermatids, suggesting a function in fertility regulation.

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.

Endoplasmic reticulum protein 19 (ERp19) family; ERp19 is also known as ERp18, a protein located in the ER containing one redox active TRX domain. Denaturation studies indicate that the reduced form is more stable than the oxidized form, suggesting that the protein is involved in disulfide bond formation. In vitro, ERp19 has been shown to possess thiol-disulfide oxidase activity which is dependent on the presence of both active site cysteines. Although described as protein disulfide isomerase (PDI)-like, the protein does not complement for PDI activity. ERp19 shows a wide tissue distribution but is most abundant in liver, testis, heart and kidney.

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.

N-acylglucosamine 2-epimerase (GlcNAc 2-epimerase); This family contains a number of eukaryotic and bacterial N-acylglucosamine 2-epimerase (GlcNAc 2-epimerase) enzymes (EC:5.1.3.8) approximately 500 residues long. This converts N-acyl-D-glucosamine to N-acyl-D-mannosamine.

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.

(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
