Arsenite4
  • Arsenate reductase (glutaredoxin) (EC 1.20.4.1) is an enzyme that catalyzes the chemical reaction arsenate + glutaredoxin ⇌ {\displaystyle \rightleftharpoons } arsenite + glutaredoxin disulfide + H2O Thus, the two substrates of this enzyme are arsenate and glutaredoxin, whereas its 3 products are arsenite, glutaredoxin disulfide, and water. (wikipedia.org)
  • Arsenic is found in mainly in two forms: arsenite and arsenate. (easyreport.in)
  • Both forms are toxic: arsenite disrupts sulfhydryl groups of proteins and interferes with enzyme function, whereas arsenate acts as a phosphate analog and can interfere with phosphate uptake and transport. (easyreport.in)
  • Resistance to arsenic species in both Gram-positive and Gram-negative organisms results from energy-dependent efflux of either arsenate or arsenite from the cell, mediated by the ars operon [4-6]. (easyreport.in)
Arsenic1
  • Wood preservative chromated copper arsenate, arsenic pesticides, glass production, pharmaceuticals, non-ferrous alloys and wastes of leather industries. (easyreport.in)
Enzyme1
  • The systematic name of this enzyme class is glutaredoxin:arsenate oxidoreductase. (wikipedia.org)
Proteins1
  • The the Cysteine containing enzymatically active version of the domain is also found in the CDC25 class of protein phosphatases and a variety of proteins such as sulfide dehydrogenases and stress proteins such as Senesence specific protein 1 in plants, PspE and GlpE in bacteria and cyanide and arsenate resistance proteins. (embl.de)
Resistance1
  • Based on the results of this analysis, we also predict that the budding yeast arsenate resistance protein Acr2 and the ORF Ygr203w encode protein phosphatases with catalytic properties similar to that of the Cdc25 family. (embl.de)
