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:0000256|HAMAP-Rule:MF_01216}.
CC -!- FUNCTION: Quinone reductase that provides resistance to thiol-specific
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 Evidence={ECO:0000256|HAMAP-Rule:MF_01216};
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}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
