Analysis of its complete genome indicates that it lacks a conventional arsenite oxidase (Aox), but instead possesses two operons that each encode a putative respiratory arsenate reductase (Arr). (usgs.gov)
It contained three distinct arsenic resistance gene clusters (ars operons), while no respiratory arsenate reductase gene (arr) was identified. (elsevierpure.com)
2004). The respiratory arsenate-reductase of B. selenitireducens is membrane-associated and is a heterodimer of the DMSO family of Mo-containing enzymes (Afkar et al, 2003). (doe.gov)

Arsenite4
Here we show that one homolog is expressed under chemolithoautotrophic conditions and exhibits both arsenite oxidase and arsenate reductase activity. (usgs.gov)
These analyses revealed that, for catalytic metabolism of arsenate, the arsenate binding-loop (AB-loop) and residues Phe-53, Phe-54, Cys-134, Cys-136, Cys-141, Cys-145, and Lys-135 are essential for reducing arsenate to arsenic intermediates (arsenylated enzyme-substrate intermediates) and arsenite in plants. (diva-portal.org)
Thus, functional predictions suggest that the ACR2 protein is involved in the conversion of arsenate to arsenite in plant cells. (diva-portal.org)
Sequence analysis of a clone conferring resistance to both sodium arsenite and sodium arsenate revealed homologues to the arsR (regulatory repressor), arsB (membrane located arsenite pump), arsC (arsenate reductase), arsD (second regulatory repressor and a metallochaperone) and arsA (ATPase) genes from known arsenic resistance operons.

ArsC1
Furthermore, five isolates contained the arsenate reductase gene (arsC). (bvsalud.org)
Arsenic1
The thermophilic bacterium Thermus thermophilus HB27 encodes chromosomal arsenate reductase (TtArsC), the enzyme responsible for resistance to the harmful effects of arsenic. (cnr.it)
Azurin1
Arsenate reductase may refer to: Arsenate reductase (azurin) Arsenate reductase (cytochrome c) Arsenate reductase (donor) Arsenate reductase (glutaredoxin) This set index page lists enzyme articles associated with the same name. (wikipedia.org)
2) S -mycothiolation and protein regeneration occur via Mrx1 (mycoredoxin 1) /MSH/Mtr and thioredoxin/Thioredoxin reductase (Trx /TrxR) pathway. (encyclopedia.pub)
Organism1
It is the only well-described organism that can respire toxic selenite in addition to arsenate, nitrate, nitrite, TMAO, fumarate, and has some capacity for microaerophilic growth. (doe.gov)
Sulfite1
Most of parameters involved in ROS and MG metabolisms had similar variation trends and degrees between the Mg-deficient lower leaves and roots, but several parameters (namely glutathione S-transferase, sulfite reductase, ascorbate and dehydroascorbate) displayed the opposite variation trends. (biomedcentral.com)
Oxidase1
Thus Arr can function as a reductase or oxidase. (usgs.gov)
Synthase1
Previously, our in silico analyses identified four candidate genes that might be involved in uptake and/or accumulation of arsenics in plants: arsenate reductase 2 ( ACR2 ), phytochelatin synthase 1 ( PCS1 ) and two multi-drug resistant proteins ( MRP1 and MRP2 ) [Lund et al. (diva-portal.org)
Bacterial1
Sixteen arsenate-tolerant bacterial strains were isolated from the P. vittata rhizosphere, a majority of which belong to the Bacillus genus, and of this majority only two have been previously associated with As. (bvsalud.org)
Hydroperoxide reductase subunit1

Reduce arsenate1
This organism can reduce arsenate, selenate, and selenite, making it a potential bioremediation agent. (up.ac.za)
As3MT1
AS3MT knockout mice treated with arsenate retain a significantly greater body burden of As, and excrete less As in urine, than wild-type mice (Hughes et al. (medscape.com)
Arsenate is taken up by phosphate transporters. (qub.ac.uk)
Reduction2
Reduction of arsenate in the purine nucleoside arsenolysis reaction required both PNP and dihydrolipoic acid (DHLP). (nih.gov)
The PNP rate of reduction of arsenate with the reducing agents GSH or ascorbic acid was negligible compared to that with the naturally occurring dithiol DHLP and synthetic dithiols such as BAL (British anti-lewisite), DMPS (2,3-dimercapto-1-propanesulfonate), or DTT (alpha-dithiothreitol). (nih.gov)
Respiratory1
The respiratory arsenate reductase has been purified, and is able to function at high pH and alkalinity. (up.ac.za)
Genes1
Via a genome-wide association study, we identified a high level of mutational burden in methionine sulfoxide reductase genes relative to the most closely related Earth strains. (biomedcentral.com)
Activity1
Among the mycorrhizal inoculum, the mixed inoculum IM/GM promoted substantially higher mycorrhizal colonization and arsenate reductase activity in P. vittata than C. dactylon, among all As levels. (edu.hk)
Functions1
One type of arsenate reductase has been identified, but its in planta functions remain to be investigated. (qub.ac.uk)
