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.
