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.

 4-48 9.28e-23

Arsenate Reductase (ArsC) family, ArsC subfamily; arsenic reductases similar to that encoded by arsC on the R733 plasmid of Escherichia coli. E. coli ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], the first step in the detoxification of arsenic, using reducing equivalents derived from glutathione (GSH) via glutaredoxin (GRX). ArsC contains a single catalytic cysteine, within a thioredoxin fold, that forms a covalent thiolate-As(V) intermediate, which is reduced by GRX through a mixed GSH-arsenate intermediate. 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.

 4-48 3.43e-17

arsenate reductase (glutaredoxin); This model describes a distinct clade, including ArsC itself, of the broader ArsC family described by Pfam pfam03960. This clade is almost completely restricted to the Proteobacteria. An anion-translocating ATPase has been identified as the product of the arsenical resistance operon of resistance plasmid R773. When expressed in Escherichia coli this ATP-driven oxyanion pump catalyses extrusion of the oxyanions arsenite, antimonite and arsenate. The pump is composed of two polypeptides, the products of the arsA and arsB genes. The pump alone produces resistance to arsenite and antimonite. This protein, ArsC, catalyzes the reduction of arsenate to arsenite, and thus extends resistance to include arsenate. [Cellular processes, Detoxification]

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.

transcriptional regulator, Spx/MgsR family; This model represents a portion of the proteins within the larger set covered by pfam03960. That larger family includes a glutaredoxin-dependent arsenate reductase (TIGR00014). Characterized members of this family include Spx and MgsR from Bacillus subtili. Spx is a global regulator for response to thiol-specific oxidative stress. It interacts with RNA polymerase. MgsR (modulator of the general stress response, also called YqgZ) provides a second level of regulation for more than a third of the proteins in the B. subtilis general stress regulon controlled by Sigma-B.
