Protein attributes

Sequence length	178 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the reductive cleavage of azo bond in aromatic azo compounds to the corresponding amines. Requires NADPH as an electron donor for its activity. Compounds with paired naphthalene groups coupled with the azo group are good substrates, with the following preference order: Rocceline > Sumifix Black B > Solar Orange.
Catalytic activity	N,N-dimethyl-1,4-phenylenediamine + aniline + 2 NADP+ = 4-(dimethylamino)azobenzene + 2 NADPH.
Subunit structure	Monomer.
Induction	Constitutively expressed.
Sequence similarities	Belongs to the azoreductase type 2 family.
biophysicochemical properties	Temperature dependence: Optimum temperature is 70 degrees Celsius.
