DSBA-like thioredoxin domain; This family contains a diverse set of proteins with a thioredoxin-like structure pfam00085. This family also includes 2-hydroxychromene-2-carboxylate (HCCA) isomerase enzymes catalyze one step in prokaryotic polyaromatic hydrocarbon (PAH) catabolic pathways. This family also contains members with functions other than HCCA isomerization, such as Kappa family GSTs, whose similarity to HCCA isomerases was not previously recognized. The sequence Swiss:O07298 has been annotated as a dioxygenase but is almost certainly an HCCA isomerase enzyme. Similarly, the sequence Swiss:Q9ZI67 has been annotated as a dehydrogenase, but is most probably also an HCCA isomerase enzyme. In addition, the Rhizobium leguminosarum Swiss:Q52782 protein has been annotated as a putative glycerol-3-phosphate transfer protein, but is also most likely to be an HCCA isomerase enzyme.

DsbA family, 2-hydroxychromene-2-carboxylate (HCCA) isomerase subfamily; HCCA isomerase is a glutathione (GSH) dependent enzyme involved in the naphthalene catabolic pathway. It converts HCCA, a hemiketal formed spontaneously after ring cleavage of 1,2-dihydroxynapthalene by a dioxygenase, into cis-o-hydroxybenzylidenepyruvate (cHBPA). This is the fourth reaction in a six-step pathway that converts napthalene into salicylate. HCCA isomerase is unique to bacteria that degrade polycyclic aromatic compounds. It is closely related to the eukaryotic protein, GSH transferase kappa (GSTK).

DsbA family; consists of DsbA and DsbA-like proteins, including DsbC, DsbG, glutathione (GSH) S-transferase kappa (GSTK), 2-hydroxychromene-2-carboxylate (HCCA) isomerase, an oxidoreductase (FrnE) presumed to be involved in frenolicin biosynthesis, a 27-kDa outer membrane protein, and similar proteins. Members of this family contain a redox active CXXC motif (except GSTK and HCCA isomerase) imbedded in a TRX fold, and an alpha helical insert of about 75 residues (shorter in DsbC and DsbG) relative to TRX. DsbA is involved in the oxidative protein folding pathway in prokaryotes, catalyzing disulfide bond formation of proteins secreted into the bacterial periplasm. DsbC and DsbG function as protein disulfide isomerases and chaperones to correct non-native disulfide bonds formed by DsbA and prevent aggregation of incorrectly folded proteins.

DsbA family, Com1-like subfamily; composed of proteins similar to Com1, a 27-kDa outer membrane-associated immunoreactive protein originally found in both acute and chronic disease strains of the pathogenic bacteria Coxiella burnetti. It contains a CXXC motif, assumed to be imbedded in a DsbA-like structure. Its homology to DsbA suggests that the protein is a protein disulfide oxidoreductase. The role of such a protein in pathogenesis is unknown.

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.

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
