catechol 1,2-dioxygenase, proteobacterial; Members of this family known so far are catechol 1,2-dioxygenases of the Proteobacteria. They are distinct from catechol 1,2-dioxygenases and chlorocatechol 1,2-dioxygenases of the Actinobacteria, which are quite similar to each other and resolved by separate models. This enzyme catalyzes intradiol cleavage in which catechol + O2 becomes cis,cis-muconate. Catechol is an intermediate in the catabolism of many different aromatic compounds, as is the alternative intermediate protocatechuate. In Acinetobacter lwoffii, two isozymes are present with abilities, differing somewhat, to act on catechol analogs 3-methylcatechol, 4-methylcatechol, 4-methoxycatechol, and 4-chlorocatechol.

Catechol intradiol dioxygenases can be divided into several subgroups according to their substrate specificity for catechol, chlorocatechols and hydroxyquinols. Almost all members of this family are homodimers containing one ferric ion (Fe3+) per monomer. They belong to the intradiol dioxygenase family, a family of mononuclear non-heme iron intradiol-cleaving enzymes that catalyze the oxygenation of catecholates to aliphatic acids via the cleavage of aromatic rings.

chlorocatechol 1,2-dioxygenases (1,2-CCDs) (type II enzymes) are homodimeric intradiol dioxygenases that degrade chlorocatechols via the addition of molecular oxygen and the subsequent cleavage between two adjacent hydroxyl groups. This reaction is part of the modified ortho-cleavage pathway which is a central oxidative bacterial pathway that channels chlorocatechols, derived from the degradation of chlorinated benzoic acids, phenoxyacetic acids, phenols, benzenes, and other aromatics into the energy-generating tricarboxylic acid pathway.

Intradiol dioxygenases catalyze the critical ring-cleavage step in the conversion of catecholate derivatives to citric acid cycle intermediates. This family contains catechol 1,2-dioxygenases and protocatechuate 3,4-dioxygenases which are mononuclear non-heme iron enzymes that catalyze the oxygenation of catecholates to aliphatic acids via the cleavage of aromatic rings. The members are intradiol-cleaving enzymes which break the catechol C1-C2 bond and utilize Fe3+, as opposed to the extradiol-cleaving enzymes which break the C2-C3 or C1-C6 bond and utilize Fe2+ and Mn+. Catechol 1,2-dioxygenases are mostly homodimers with one catalytic ferric ion per monomer. Protocatechuate 3,4-dioxygenases form more diverse oligomers.
