| + | [https://www.uniprot.org/uniprot/CHRR_ECOLI CHRR_ECOLI] Involved in the protection against chromate toxicity. Catalyzes the transfer of three electrons to Cr(6+) producing Cr(3+) and one electron to molecular oxygen without producing the toxic Cr(5+) species and only producing a minimal amount of reactive oxygen species (ROS). It can also reduce quinones, potassium ferricyanide, 2,6-dichloroindophenol, V(5+), Mo(6+), methylene blue and cytochrome c. The quinone reductase activity may protect against oxidative stress by preventing redox cycling of quinones which would otherwise generate ROS and by maintaining a pool of reduced quinone in the cell that is able to quench ROS directly. It is able to use both NAD or NADP equally well.<ref>PMID:14766567</ref> <ref>PMID:16621832</ref> <ref>PMID:17088379</ref> <ref>PMID:22558308</ref> | ||
