General annotation (Comments)

Function

Shows a preference for catechols with groups immediately adjacent to the hydroxyl substituents.

Catalytic activity

Biphenyl-2,3-diol + O2 = 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate.

Cofactor

Binds 1 Fe2+ ion per subunit.

Pathway

Xenobiotic degradation; biphenyl degradation; 2-hydroxy-2,4-pentadienoate and benzoate from biphenyl: step 3/4.

Subunit structure

Homooctamer. The enzyme is composed of two planar tetramers rotated at 45 degrees relative to each other, with a channel in the middle. Ref.3

Sequence similarities

Belongs to the extradiol ring-cleavage dioxygenase family.

Biophysicochemical properties

Kinetic parameters:

Substrate inhibition occurs at 300 µM (+/- 20 µM).

KM=7 µM for biphenyl-2,3-diol

pH dependence:

Optimum pH is 8.0.
