Thioredoxin-coupled arsenate reductase; Catalyzes the reduction of arsenate [As(V)] to arsenite [As(III)]. In vitro, can dephosphorylate para- nitrophenyl phosphate (pNPP). Belongs to the low molecular weight phosphotyrosine protein phosphatase family. Thioredoxin-coupled ArsC subfamily.

Alkyl hydroperoxide reductase (large subunit); Transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity).

Superoxide dismutase; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems; Belongs to the iron/manganese superoxide dismutase family.

Putative thioredoxin or thiol-disulfide isomerase; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions; Belongs to the thioredoxin family.

Transcriptional regulator (Fur family); Hydrogen and organic peroxide sensor. Represses the expression of a regulon of peroxide-inducible genes such as katA, ahpC, ahpF, the heme biosynthesis operon (hemAXCDBL), fur, perR, zosA and mrgA; Belongs to the Fur family.

Transcriptional terminator Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.

Putative thiol management oxidoreductase component; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.

ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a limited peptidase activity in the absence of ATP-binding subunits ClpC, ClpE or ClpX. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity). ClpXP is involved in the complete degradation of the site-2 clipped anti-sigma-W factor RsiW. This results in the release of SigW and the transcriptional activation of genes under the control of the sigma-W factor. Probably the major protease that degrades prot [...]

Alkyl hydroperoxide reductase (small subunit); Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
