CC   -!- FUNCTION: Quinone reductase that provides resistance to thiol-specific
CC       stress caused by electrophilic quinones. {ECO:0000255|HAMAP-
CC       Rule:MF_01216}.
CC   -!- FUNCTION: Also exhibits azoreductase activity. Catalyzes the reductive
CC       cleavage of the azo bond in aromatic azo compounds to the corresponding
CC       amines. {ECO:0000255|HAMAP-Rule:MF_01216}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 a quinone + H(+) + NADH = 2 a 1,4-benzosemiquinone + NAD(+);
