Protein attributes

Sequence length	193 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Component of the naphthalene dioxygenase (NDO) multicomponent enzyme system which catalyzes the incorporation of both atoms of molecular oxygen into naphthalene to form cis-naphthalene dihydrodiol. The beta subunit may be responsible for the substrate specificity of the enzyme.
Catalytic activity	Naphthalene + NADH + O2 = (1R,2S)-1,2-dihydronaphthalene-1,2-diol + NAD+.
Cofactor	Binds 1 2Fe-2S cluster Probable. Binds 1 iron ion Probable.
Pathway	Aromatic compound metabolism; naphthalene degradation.
Subunit structure	Naphthalene dioxygenase (NDO) multicomponent enzyme system is composed of an electron transfer component and an iron sulfur protein (ISP). The electron transfer component is composed of ferredoxin reductase (ndoR) and ferredoxin (ndoA), and ISP is composed of a large alpha subunit (ndoB) and a small beta subunit (ndoC).
Sequence similarities	Belongs to the bacterial ring-hydroxylating dioxygenase beta subunit family.
