Protein Disulfide Oxidoreductases and Other Proteins with a Thioredoxin fold; The thioredoxin (TRX)-like superfamily is a large, diverse group of proteins containing a TRX fold. Many members contain a classic TRX domain with a redox active CXXC motif. They function as protein disulfide oxidoreductases (PDOs), altering the redox state of target proteins via the reversible oxidation of their active site dithiol. The PDO members of this superfamily include the families of TRX, protein disulfide isomerase (PDI), tlpA, glutaredoxin, NrdH redoxin, and bacterial Dsb proteins (DsbA, DsbC, DsbG, DsbE, DsbDgamma). Members of the superfamily that do not function as PDOs but contain a TRX-fold domain include phosducins, peroxiredoxins, glutathione (GSH) peroxidases, SCO proteins, GSH transferases (GST, N-terminal domain), arsenic reductases, TRX-like ferredoxins and calsequestrin, among others.

TraF-like protein; This protein is related to the F-type conjugation system pilus assembly proteins TraF (TIGR02739)and TrbB (TIGR02738) both of which exhibit a thioredoxin fold. The protein represented by this model has the same length and architecture as TraF, but lacks the CXXC-motif found in TrbB and believed to be responsible for the disulfide isomerase activity of that protein.

54-289 2.45e-66

F plasmid transfer operon protein; TraF protein undergoes proteolytic processing associated with export. The 19 amino acids at the amino terminus of the polypeptides appear to constitute a typical membrane leader peptide - not included in this family, while the remainder of the molecule is predicted to be primarily hydrophilic in character. F plasmid TraF and TraH are required for F pilus assembly and F plasmid transfer, and they are both localized to the outer membrane in the presence of the complete F transfer region, especially TraV, the putative anchor.
