Cystine reductase gene
WebIn enzymology, a cystine reductase(EC1.8.1.6) is an enzymethat catalyzesthe chemical reaction 2 L-cysteine + NAD+⇌{\displaystyle \rightleftharpoons }L-cystine + NADH + H+ Thus, the two substratesof this enzyme are L-cysteineand NAD+, whereas its 3 … WebRegeneration of the ribonucleotide reductase is accomplished in Escherichia coli and in mammals by thioredoxin, a dithiol polypeptide (M.W. 12,000) coenzyme, which also plays a role in other protein disulfide reductase reactions. In thioredoxin, two cysteine residues in the sequence –Cys–Gly–Pro–Cys are converted to cystine.

WebMar 16, 2011 · The reducing agent reacts with cystine in the culture medium and forms a mixed disulfide, and thereby releases cysteine. These reaction products go into cells via neutral amino acid transporters and contribute to the maintenance of adequate GSH levels in the cells. Fig. 2 The cystine/cysteine redox cycle driven by system x − c . WebThe arsenic detoxification mechanism is controlled by ars genes that encode proteins that facilitate As (V) reduction via a cytoplasmic enzyme arsenate reductase into As (III) followed by As removal from the cell by an efflux pump [25,80]. The two most common operons contain either five ( arsRDABC) or three ( arsRBC) genes.
WebCystine reductase activity has been demonstrated in preparations from pea seeds and two different strains of yeasts (bakers' yeast and Candida alticuns). Cystine is not reduced by the glutathione reductase-TPNH system of pea seeds or yeasts. Cystine reductase and glutathione reductase are not inhibited by penicillin, streptomycin, or fradicin.
