Comments

FUNCTION: Catalyzes both the oxidation of benzene and toluene. The beta subunit may be responsible for the substrate specificity of the enzyme.
CATALYTIC ACTIVITY: Benzene + NADH + O₂ = cis-cyclohexa-3,5-diene-1,2-diol + NAD⁺.
CATALYTIC ACTIVITY: Toluene + NADH + O₂ = (1S,2R)-3-methylcyclohexa-3,5-diene-1,2-diol + NAD⁺.
COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity).
COFACTOR: Binds 1 iron ion per subunit (By similarity).
PATHWAY: Aromatic compound metabolism; benzene degradation; catechol from benzene: step 1/2 .
PATHWAY: Xenobiotic degradation; toluene degradation .
PATHWAY: Xenobiotic degradation; xylene degradation .
SUBUNIT: This dioxygenase system consists of four proteins: the two subunits of the hydroxylase component (bnzA and bnzB), a ferredoxin (bnzC) and a ferredoxin reductase (bnzD).
SIMILARITY: Belongs to the bacterial ring-hydroxylating dioxygenase beta subunit family.
