 5-171 1.96e-66

type-F conjugative transfer system pilin assembly thiol-disulfide isomerase TrbB; This protein is part of a large group of proteins involved in conjugative transfer of plasmid DNA, specifically the F-type system. This protein has been predicted to contain a thioredoxin fold, contains a conserved pair of cysteines and has been shown to function as a thiol disulfide isomerase by complementation of an Ecoli DsbA defect. The protein is believed to be involved in pilin assembly. The protein is closely related to TraF (TIGR02739) which is somewhat longer, lacks the cysteine motif and is apparently not functional as a disulfide bond isomerase.

 67-157 2.94e-11

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.

 72-114 3.16e-04

DsbA family, DsbC and DsbG subfamily; V-shaped homodimeric proteins containing a redox active CXXC motif imbedded in a TRX fold. They function as protein disulfide isomerases and chaperones in the bacterial periplasm to correct non-native disulfide bonds formed by DsbA and prevent aggregation of incorrectly folded proteins. DsbC and DsbG are kept in their reduced state by the cytoplasmic membrane protein DsbD, which utilizes the TRX/TRX reductase system in the cytosol as a source of reducing equivalents. DsbG differ from DsbC in that it has a more limited substrate specificity, and it may preferentially act later in the folding process to catalyze disulfide rearrangements in folded or partially folded proteins. Also included in the alignment is the predicted protein TrbB, whose gene was sequenced from the enterohemorrhagic E. coli type IV pilus gene cluster, which is required for efficient plasmid transfer.

 72-114 3.16e-04

DsbA family, DsbC and DsbG subfamily; V-shaped homodimeric proteins containing a redox active CXXC motif imbedded in a TRX fold. They function as protein disulfide isomerases and chaperones in the bacterial periplasm to correct non-native disulfide bonds formed by DsbA and prevent aggregation of incorrectly folded proteins. DsbC and DsbG are kept in their reduced state by the cytoplasmic membrane protein DsbD, which utilizes the TRX/TRX reductase system in the cytosol as a source of reducing equivalents. DsbG differ from DsbC in that it has a more limited substrate specificity, and it may preferentially act later in the folding process to catalyze disulfide rearrangements in folded or partially folded proteins. Also included in the alignment is the predicted protein TrbB, whose gene was sequenced from the enterohemorrhagic E. coli type IV pilus gene cluster, which is required for efficient plasmid transfer.

 62-144 8.35e-04

TlpA-like family; composed of TlpA, ResA, DsbE and similar proteins. TlpA, ResA and DsbE are bacterial protein disulfide reductases with important roles in cytochrome maturation. They are membrane-anchored proteins with a soluble TRX domain containing a CXXC motif located in the periplasm. The TRX domains of this family contain an insert, approximately 25 residues in length, which correspond to an extra alpha helix and a beta strand when compared with TRX. TlpA catalyzes an essential reaction in the biogenesis of cytochrome aa3, while ResA and DsbE are essential proteins in cytochrome c maturation. Also included in this family are proteins containing a TlpA-like TRX domain with domain architectures similar to E. coli DipZ protein, and the N-terminal TRX domain of PilB protein from Neisseria which acts as a disulfide reductase that can recylce methionine sulfoxide reductases.

 73-99 8.76e-04

TRX family; composed of two groups: Group I, which includes proteins that exclusively encode a TRX domain; and Group II, which are composed of fusion proteins of TRX and additional domains. Group I TRX is a small ancient protein that alter the redox state of target proteins via the reversible oxidation of an active site dithiol, present in a CXXC motif, partially exposed at the protein's surface. TRX reduces protein disulfide bonds, resulting in a disulfide bond at its active site. Oxidized TRX is converted to the active form by TRX reductase, using reducing equivalents derived from either NADPH or ferredoxins. By altering their redox state, TRX regulates the functions of at least 30 target proteins, some of which are enzymes and transcription factors. It also plays an important role in the defense against oxidative stress by directly reducing hydrogen peroxide and certain radicals, and by serving as a reductant for peroxiredoxins. At least two major types of functional TRXs have been reported in most organisms; in eukaryotes, they are located in the cytoplasm and the mitochondria. Higher plants contain more types (at least 20 TRX genes have been detected in the genome of Arabidopsis thaliana), two of which (types f amd m) are located in the same compartment, the chloroplast. Also included in the alignment are TRX-like domains which show sequence homology to TRX but do not contain the redox active CXXC motif. Group II proteins, in addition to either a redox active TRX or a TRX-like domain, also contain additional domains, which may or may not possess homology to known proteins.

 53-101 2.09e-03

Peroxiredoxin (PRX)-like 1 family; hypothetical proteins that show sequence similarity to PRXs. Members of this group contain a conserved cysteine that aligns to the first cysteine in the CXXC motif of TRX. This does not correspond to the peroxidatic cysteine found in PRXs, which aligns to the second cysteine in the CXXC motif of TRX. In addition, these proteins do not contain the other two conserved residues of the catalytic triad of PRX. PRXs confer a protective antioxidant role in cells through their peroxidase activity in which hydrogen peroxide, peroxynitrate, and organic hydroperoxides are reduced and detoxified using reducing equivalents derived from either thioredoxin, glutathione, trypanothione and AhpF.
