Numerous researchers have identified chromate reductase activity by … WebChromate reductase, the central enzyme involved in bioreduction of Cr(VI) to Cr(III) may be both intracellular as well as extracellular in nature. Most of the chromate reductase enzyme belongs to the oxidoreductase group such as nitroreductase, iron reductase, quinone reductase, hydrogenase, flavin reductase, as well as NAD(P)H-dependent ...
WebFeb 6, 2024 · The induction of chromate stress AMM-medium stimulated bacterial cells to synthesized chromate reductase to eliminate toxic Cr (VI). This suggested that chromate reductase was produced after exposure to Cr (VI) rather than continuous production. Strain UT25 showed maximum cell density under non-stress conditions in LB medium. Webally characterized a putative chromate reductase (Gh-ChrR) from the recently sequenced genome of Gluconacetobacter hansenii [16]. Gh-ChrR belongs to the superfamily of NAD(P)H-dependent FMN reductases that catalyze the metabolic detoxification of quinones and their derivatives to hydroquinones, using NAD(P)H as the electron donor.
