36-242 1.91e-84

Glutaredoxin-like domain protein; This family of archaeal proteins contains a C-terminal domain with homology to bacterial and eukaryotic glutaredoxins, including a CPYC motif. There is an N-terminal domain which has even more distant homology to glutaredoxins. The name "glutaredoxin" may be inappropriate in the sense of working in tandem with glutathione and glutathione reductase which may not be present in the archaea. The overall domain structure appears to be related to bacterial alkylhydroperoxide reductases, but the homology may be distant enough that the function of this family is wholly different.

36-142 9.41e-38

Pyrococcus furiosus protein disulfide oxidoreductase (PfPDO)-like family, N-terminal TRX-fold subdomain; composed of proteins with similarity to PfPDO, a redox active thermostable protein believed to be the archaeal counterpart of bacterial DsbA and eukaryotic protein disulfide isomerase (PDI), which are both involved in oxidative protein folding. PfPDO contains two redox active CXXC motifs in two contiguous TRX-fold subdomains. The active site in the N-terminal TRX-fold subdomain is required for isomerase but not for reductase activity of PfPDO. The exclusive presence of PfPDO-like proteins in extremophiles may suggest that they have a special role in adaptation to extreme conditions.

Thioredoxin (TRX)-Glutaredoxin (GRX)-like family; composed of archaeal and bacterial proteins ...
163-229 2.45e-26

Thioredoxin (TRX)-Glutaredoxin (GRX)-like family; composed of archaeal and bacterial proteins that show similarity to both TRX and GRX, including the C-terminal TRX-fold subdomain of Pyrococcus furiosus protein disulfide oxidoreductase (PfPDO). All members contain a redox-active CXXC motif and may function as PDOs. The archaeal proteins Mj0307 and Mt807 show structures more similar to GRX, but activities more similar to TRX. Some members of the family are similar to PfPDO in that they contain a second CXXC motif located in a second TRX-fold subdomain at the N-terminus; the superimposable N- and C-terminal TRX subdomains form a compact structure. PfPDO is postulated to be the archaeal counterpart of bacterial DsbA and eukaryotic protein disulfide isomerase (PDI). The C-terminal CXXC motif of PfPDO is required for its oxidase, reductase and isomerase activities. Also included in the family is the C-terminal TRX-fold subdomain of the N-terminal domain (NTD) of bacterial AhpF, which has a similar fold as PfPDO with two TRX-fold subdomains but without the second CXXC motif.

150-228 7.40e-13

TRX-GRX-like family, Alkyl hydroperoxide reductase F subunit (AhpF) N-terminal domain (NTD) subfamily, C-terminal TRX-fold subdomain; AhpF is a homodimeric flavoenzyme which catalyzes the NADH-dependent reduction of the peroxiredoxin AhpC, which then reduces hydrogen peroxide and organic hydroperoxides. AhpF contains an NTD containing two contiguous TRX-fold subdomains similar to Pyrococcus furiosus protein disulfide oxidoreductase (PfPDO). It also contains a catalytic core similar to TRX reductase containing FAD and NADH binding domains with an active site disulfide. The proposed mechanism of action of AhpF is similar to a TRX/TRX reductase system. The flow of reducing equivalents goes from NADH -> catalytic core of AhpF -> NTD of AhpF -> AhpC -> peroxide substrates. The catalytic CXXC motif of the NTD of AhpF is contained in its C-terminal TRX subdomain.

small redox-active disulfide protein 1; This protein is homologous to a family of proteins that includes thioredoxins, glutaredoxins, protein-disulfide isomerases, and others, some of which have several such domains. The sequence of this protein at the redox-active disufide site, CPYC, matches glutaredoxins rather than thioredoxins, although its overall sequence seems closer to thioredoxins. It is suggested to be a ribonucleotide-reducing system component distinct from thioredoxin or glutaredoxin. [Unknown function, General]

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.

165-221 9.82e-04

Thioredoxin (TRX) superfamily; 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 TRX, protein disulfide isomerase (PDI), tlpA-like, glutaredoxin, NrdH redoxin, and the bacterial Dsb (DsbA, DsbC, DsbG, DsbE, DsbDgamma) protein families. Members of the superfamily that do not function as PDOs but contain a TRX-fold domain include phosducins, peroxiredoxins and glutathione (GSH) peroxidases, SCO proteins, GSH transferases (GST, N-terminal domain), arsenic reductases, TRX-like ferredoxins and calsequestrin, among others.

Thioredoxin (TRX)-Glutaredoxin (GRX)-like family; composed of archaeal and bacterial proteins that show similarity to both TRX and GRX, including the C-terminal TRX-fold subdomain of Pyrococcus furiosus protein disulfide oxidoreductase (PfPDO). All members contain a redox-active CXXC motif and may function as PDOs. The archaeal proteins Mj0307 and Mt807 show structures more similar to GRX, but activities more similar to TRX. Some members of the family are similar to PfPDO in that they contain a second CXXC motif located in a second TRX-fold subdomain at the N-terminus; the superimposable N- and C-terminal TRX subdomains form a compact structure. PfPDO is postulated to be the archaeal counterpart of bacterial DsbA and eukaryotic protein disulfide isomerase (PDI). The C-terminal CXXC motif of PfPDO is required for its oxidase, reductase and isomerase activities. Also included in the family is the C-terminal TRX-fold subdomain of the N-terminal domain (NTD) of bacterial AhpF, which has a similar fold as PfPDO with two TRX-fold subdomains but without the second CXXC motif.

167-225 2.37e-03

NrdH-redoxin (NrdH) family; NrdH is a small monomeric protein with a conserved redox active CXXC motif within a TRX fold, characterized by a glutaredoxin (GRX)-like sequence and TRX-like activity profile. In vitro, it displays protein disulfide reductase activity that is dependent on TRX reductase, not glutathione (GSH). It is part of the NrdHIEF operon, where NrdEF codes for class Ib ribonucleotide reductase (RNR-Ib), an efficient enzyme at low oxygen levels. Under these conditions when GSH is mostly conjugated to spermidine, NrdH can still function and act as a hydrogen donor for RNR-Ib. It has been suggested that the NrdHEF system may be the oldest RNR reducing system, capable of functioning in a microaerophilic environment, where GSH was not yet available. NrdH from Corynebacterium ammoniagenes can form domain-swapped dimers, although it is unknown if this happens in vivo. Domain-swapped dimerization, which results in the blocking of the TRX reductase binding site, could be a mechanism for regulating the oxidation state of the protein.

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.
