EC 1.7.1.17 Details

show Brenda entry

EC number

1.7.1.17

Accepted name

FMN-dependent NADH-azoreductase

Reaction

anthranilate + N,N-dimethyl-1,4-phenylenediamine + 2 NAD⁺ = 2-(4-dimethylaminophenyl)diazenylbenzoate + 2 NADH + 2 H⁺

Other name(s)

azoR (gene name), NADH-azoreductase

Systematic name

N,N-dimethyl-1,4-phenylenediamine, anthranilate:NAD⁺ oxidoreductase

Comment

Requires FMN. The enzyme catalyses the reductive cleavage of an azo bond in aromatic azo compounds to form the corresponding amines. Does not accept NADPH. cf. EC 1.7.1.6, azobenzene reductase.
