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.

117-200 4.62e-13

Glutaredoxin (GRX) family, GRX human class 1 and 2 (h_1_2)-like subfamily; composed of proteins similar to human GRXs, 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, which are members of this subfamily. Also included in this subfamily are the N-terminal GRX domains of proteins similar to human thioredoxin reductase 1 and 3.

118-202 7.74e-07

Glutaredoxin, GrxC family; Glutaredoxins are thioltransferases (disulfide reductases) which utilize glutathione and NADPH as cofactors. Oxidized glutathione is regenerated by glutathione reductase. Together these components compose the glutathione system. Glutaredoxins utilize the CXXC motif common to thioredoxins and are involved in multiple cellular processes including protection from redox stress, reduction of critical enzymes such as ribonucleotide reductase and the generation of reduced sulfur for iron sulfur cluster formation. Glutaredoxins are capable of reduction of mixed disulfides of glutathione as well as the formation of glutathione mixed disulfides. This family of glutaredoxins includes the E. coli protein GrxC (Grx3) which appears to have a secondary role in reducing ribonucleotide reductase (in the absence of GrxA) possibly indicating a role in the reduction of other protein disulfides.

118-189 1.86e-04

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.

Glutaredoxin (GRX) family, PKC-interacting cousin of TRX (PICOT)-like subfamily; composed of PICOT and GRX-PICOT-like proteins. The non-PICOT members of this family contain only the GRX-like domain, whereas PICOT contains an N-terminal TRX-like domain followed by one to three GRX-like domains. It is interesting to note that PICOT from plants contain three repeats of the GRX-like domain, metazoan proteins (except for insect) have two repeats, while fungal sequences contain only one copy of the domain. PICOT is a protein that interacts with protein kinase C (PKC) theta, a calcium independent PKC isoform selectively expressed in skeletal muscle and T lymphocytes. PICOT inhibits the activation of c-Jun N-terminal kinase and the transcription factors, AP-1 and NF-kB, induced by PKC theta or T-cell activating stimuli. Both GRX and TRX domains of PICOT are required for its activity. Characterized non-PICOT members of this family include CXIP1, a CAX-interacting protein in Arabidopsis thaliana, and PfGLP-1, a GRX-like protein from Plasmodium falciparum.

Glutaredoxin (GRX) family, GRX bacterial class 1 and 3 (b_1_3)-like subfamily; composed of bacterial GRXs, 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 E. coli GRX1 and GRX3, which are members of this subfamily.
