UniProtKB description:  Alternative, nonproton pumping NADH:quinone oxidoreductase that delivers electrons to the respiratory chain by oxidation of NADH and reduction of quinones, and contributes to the regeneration of NAD(+) (PubMed:26172206, PubMed:28801048). Can use DMN, a menaquinone analog, 2,3-dimethoxy-5,6-dimethyl-benzoquinone (DDB), an ubiquinone analog, or 2,3,5,6-tetramethyl-1,4-benzoquinone (Duroquinone, DQ) a plastoquinone analog as electron acceptors (PubMed:26172206).
