 4-113 2.98e-57

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.

 4-114 1.49e-50

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.

 4-98 1.78e-17

Arsenate Reductase (ArsC) family, unknown subfamily; uncharacterized proteins containing a CXXC motif with similarity to thioredoxin (TRX)-fold arsenic reductases, ArsC. Proteins containing a redox active CXXC motif like TRX and glutaredoxin (GRX) function as protein disulfide oxidoreductases, altering the redox state of target proteins via the reversible oxidation of the active site dithiol. ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], using reducing equivalents derived from glutathione via GRX, through a single catalytic cysteine.

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.

 4-99 2.46e-08

Arsenate Reductase (ArsC) family, Spx subfamily; Spx is a unique RNA polymerase (RNAP)-binding protein present in bacilli and some mollicutes. It inhibits transcription by binding to the C-terminal domain of the alpha subunit of RNAP, disrupting complex formation between RNAP and certain transcriptional activator proteins like ResD and ComA. In response to oxidative stress, Spx can also activate transcription, making it a general regulator that exerts both positive and negative control over transcription initiation. Spx has been shown to exert redox-sensitive transcriptional control over genes like trxA (TRX) and trxB (TRX reductase), genes that function in thiol homeostasis. This redox-sensitive activity is dependent on the presence of a CXXC motif, present in some members of the Spx subfamily, that acts as a thiol/disulfide switch. Spx has also been shown to repress genes in a sulfate-dependent manner independent of the presence of the CXXC motif.

Arsenate Reductase (ArsC) family, 15kD protein subfamily; composed of proteins of unknown function with similarity to thioredoxin-fold arsenic reductases, ArsC. It is encoded by an ORF present in a gene cluster associated with nitrogen fixation that also encodes dinitrogenase reductase ADP-ribosyltransferase (DRAT) and dinitrogenase reductase activating glycohydrolase (DRAG). ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], using reducing equivalents derived from glutathione via glutaredoxin, through a single catalytic cysteine.

Arsenate Reductase (ArsC) family, Yffb subfamily; Yffb is an uncharacterized bacterial protein encoded by the yffb gene, related to the thioredoxin-fold arsenic reductases, ArsC. The structure of Yffb and the conservation of the catalytic cysteine suggest that it is likely to function as a glutathione (GSH)-dependent thiol reductase. ArsC catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)], using reducing equivalents derived from GSH via glutaredoxin, through a single catalytic cysteine.
