CC   -!- FUNCTION: The beta subunit may be responsible for the substrate
CC       specificity of the enzyme.
CC   -!- CATALYTIC ACTIVITY: Biphenyl + NADH + O(2) =
CC       (1S,2R)-3-phenylcyclohexa-3,5-diene-1,2-diol + NAD(+).
CC   -!- PATHWAY: Biphenyl-polychlorinated biphenyl degradation pathway;
CC       first step.
CC   -!- SUBUNIT: Heterohexamer consisting of three BphA subunits and three
CC       BphE subunits. A ferredoxin (BphF) and a ferredoxin reductase
CC       (BphG) must be present to obtain activity.
CC   -!- SIMILARITY: Belongs to the bacterial ring-hydroxylating
CC       dioxygenase beta subunit family.
