General annotation (Comments)

Function

Plays an essential role in the utilization of numerous aromatic and hydroaromatic compounds via the beta-ketoadipate pathway.

Catalytic activity

3,4-dihydroxybenzoate + O2 = 3-carboxy-cis,cis-muconate.

Cofactor

Binds Fe3+ ion per subunit.

Pathway

Aromatic compound metabolism; beta-ketoadipate pathway; 3-carboxy-cis,cis-muconate from 3,4-dihydroxybenzoate: step 1/1.

Subunit structure

The enzyme is an oligomer of 12 copies of the alpha and beta chains.

Sequence similarities

Belongs to the intradiol ring-cleavage dioxygenase family.

Caution

Strain ATCC 23975 was originally classified as being from Pseudomonas aeruginosa.
