DsbA family, DsbA subfamily; DsbA is a monomeric thiol disulfide oxidoreductase protein containing a redox active CXXC motif imbedded in a TRX fold. It is involved in the oxidative protein folding pathway in prokaryotes, and is the strongest thiol oxidant known, due to the unusual stability of the thiolate anion form of the first cysteine in the CXXC motif. The highly unstable oxidized form of DsbA directly donates disulfide bonds to reduced proteins secreted into the bacterial periplasm. This rapid and unidirectional process helps to catalyze the folding of newly-synthesized polypeptides. To regain catalytic activity, reduced DsbA is then reoxidized by the membrane protein DsbB, which generates its disulfides from oxidized quinones, which in turn are reoxidized by the electron transport chain.

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, 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.

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).
