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(+);
CC Xref=Rhea:RHEA:65952, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57945, ChEBI:CHEBI:132124, ChEBI:CHEBI:134225;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01216};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=anthranilate + N,N-dimethyl-1,4-phenylenediamine + 2 NAD(+) =
CC 2-(4-dimethylaminophenyl)diazenylbenzoate + 2 H(+) + 2 NADH;
CC Xref=Rhea:RHEA:55872, ChEBI:CHEBI:15378, ChEBI:CHEBI:15783,
CC ChEBI:CHEBI:16567, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:71579; EC=1.7.1.17; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01216};
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01216};
CC Note=Binds 1 FMN per subunit. {ECO:0000255|HAMAP-Rule:MF_01216};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01216}.
CC -!- SIMILARITY: Belongs to the azoreductase type 1 family.
CC {ECO:0000255|HAMAP-Rule:MF_01216}.
