Protocatechuate 3,4-dioxygenase is a dioxygenase that belongs to the non-heme iron dioxygenase class. This enzyme catalyzes the cleavage of the aromatic ring of 3,4-dihydroxybenzoate by incorporating two atoms of molecular oxygen to generate β-carboxy-cis,cis-muconate. It is a key enzyme in the β-ketoadipic acid pathway, found in marine bacteria associated with Roseobacter, and can be isolated from Pseudomonas aeruginosa.
