NDC1 (Alternative NAD(P)H-ubiquinone oxidoreductase C1) is a bifunctional oxidoreductase involved in an electron flow toward the plastoglobule plastoquinone pool. It is necessary for plastochromanol-8 accumulation and for vitmain K1 (phylloquinone) biosynthesis. It also participates in the redox metabolism of plastoquinone-9 and alpha-tocopherol quinone (tocophrol recycling-intermediate).Synonymes: NAD(P)H dehydrogenase C1, Demethylphylloquinone reductase NDC1, NADH:ubiquinone reductase (non-electrogenic) NDC1
