Protein
FMN-dependent NADH-azoreductase
Organism
Escherichia coli (strain K12)
Function
Catalyzes the reductive cleavage of azo bond in aromatic azo compounds to the corresponding amines. Requires NADH, but not NADPH, as an electron donor for its activity. The enzyme can reduce ethyl red and methyl red, but is not able to convert sulfonated azo dyes.
Similarity
Belongs to the azoreductase type 1 family.
