Comments [?]

Function Quinone reductase that provides resistance to thiol-specific stress caused by electrophilic quinones.
Also exhibits azoreductase activity. Catalyzes the reductive cleavage of the azo bond in aromatic azo compounds to the corresponding amines.
Catalytic activity RHEA:65952: 2 a quinone + H(+) + NADH = 2 a 1,4-benzosemiquinone + NAD(+)
RHEA:55872: anthranilate + N,N-dimethyl-1,4-phenylenediamine + 2 NAD(+) = 2-(4-dimethylaminophenyl)diazenylbenzoate + 2 H(+) + 2 NADH
EC 1.7.1.17
Cofactor FMN
Note: Binds 1 FMN per subunit.
Subunit Homodimer.
Similarity Belongs to the azoreductase type 1 family.
