CC stress caused by electrophilic quinones. {ECO:0000256|HAMAP-
CC Rule:MF_01216}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 a quinone + H(+) + NADH = 2 a 1,4-benzosemiquinone + NAD(+);

CC Note=Binds 1 FMN per subunit. {ECO:0000256|HAMAP-Rule:MF_01216};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01216}.
CC -!- SIMILARITY: Belongs to the azoreductase type 1 family.
CC {ECO:0000256|HAMAP-Rule:MF_01216}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01216}.
