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. The actual alignment was detected with superfamily member TIGR02194: Pssm-ID: 469754 Cd Length: 72 Bit Score: 79.77 E-value: 1.38e-21

Glutaredoxin-like protein NrdH; NrdH-redoxin is a representative of a class of small redox proteins that contain a conserved CXXC motif and are characterized by a glutaredoxin-like amino acid sequence and thioredoxin-like activity profile. Unlike other the glutaredoxins to which it is most closely related, NrdH aparrently does not interact with glutathione/glutathione reductase, but rather with thioredoxin reductase to catalyze the reduction of ribonucleotide reductase.

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.

Uxx-star family glutaredoxin-like (seleno)protein; A number of proteins with glutaredoxin-like folds, a length of about 75 amino acids, and a CxxC, C/UxxT, or CxxS motif near the N-terminus end with a UXX-COOH motif. That final motif typically is missed during coding region feature prediction by genome annotation pipelines. This HMM covers proteins from several distinctive families with this feature. The seed alignment illustrates the final selenocysteine or aligned Cys or Ser residues, but the HMM also hits proteins that lack an equivalent motif at the C-terminus. This C-terminal selenocysteine-containing motif has not yet been described in the literature. Pssm-ID: 469116 [Multi-domain] Cd Length: 70 Bit Score: 44.76 E-value: 7.58e-08

4-56 | 3.13e-09 | ||
Glutaredoxin (GRX) family; composed of GRX, approximately 10 kDa in size, and proteins containing a GRX or GRX-like domain. GRX is a glutathione (GSH) dependent reductase, catalyzing the disulfide reduction of target proteins such as ribonucleotide reductase. It contains a redox active CXXC motif in a TRX fold and uses a similar dithiol mechanism employed by TRXs for intramolecular disulfide bond reduction of protein substrates. Unlike TRX, GRX has preference for mixed GSH disulfide substrates, in which it uses a monothiol mechanism where only the N-terminal cysteine is required. The flow of reducing equivalents in the GRX system goes from NADPH -> GSH reductase -> GSH -> GRX -> protein substrates. By altering the redox state of target proteins, GRX is involved in many cellular functions including DNA synthesis, signal transduction and the defense against oxidative stress. Different classes are known including human GRX1 and GRX2, as well as E. coli GRX1 and GRX3, which are members of this family. E. coli GRX2, however, is a 24-kDa protein that belongs to the GSH S-transferase (GST) family. Pssm-ID: 239017 [Multi-domain] Cd Length: 72 Bit Score: 48.23 E-value: 3.13e-09

Glutaredoxin (GRX) family, PRX5 hybrid subfamily; composed of hybrid proteins containing peroxiredoxin (PRX) and GRX domains, which is found in some pathogenic bacteria and cyanobacteria. PRXs are thiol-specific antioxidant (TSA) proteins that 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. GRX is a glutathione (GSH) dependent reductase, catalyzing the disulfide reduction of target proteins. PRX-GRX hybrid proteins from Haemophilus influenza and Neisseria meningitis exhibit GSH-dependent peroxidase activity. The flow of reducing equivalents in the catalytic cycle of the hybrid protein goes from NADPH -> GSH reductase -> GSH -> GRX domain of hybrid -> PRX domain of hybrid -> peroxide substrate.

Arsenate Reductase (ArsC) family; composed of TRX-fold arsenic reductases and similar proteins including the transcriptional regulator, Spx. ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], using reducing equivalents derived from glutathione (GSH) via glutaredoxin (GRX), through a single catalytic cysteine. This family of predominantly bacterial enzymes is unrelated to two other families of arsenate reductases which show similarity to low-molecular-weight acid phosphatases and phosphotyrosyl phosphatases. Spx is a general regulator that exerts negative and positive control over transcription initiation by binding to the C-terminal domain of the alpha subunit of RNA polymerase.
