Catechol 12- dioxygenase (EC 1.13.11.1 12-CTD catechol-oxygen 12-oxidoreductase 12-pyrocatechase catechase catechol 12-oxygenase catechol dioxygenase pyrocatechase pyrocatechol 12-dioxygenase CD I CD II) is an enzyme that catalyzes the oxidative ring cleavage of catechol to form ciscis-muconic acid:More specifically 12-CTD is an intradiol dioxygenase a family of catechol dioxygenases that cleaves the bond between the phenolic hydroxyl groups of catechol using an Fe3+ cofactor.Thus far 12-CTD has been observed to exist in the following species of soil bacteria: Pseudomonas sp. Pseudomonas fluorescens Aspergillus niger Brevibacterium fuscum Acinetobacter calcoaceticus Trichosporon cutaneum Rhodococcus erythropolis Frateuria sp. Rhizobium trifolii Pseudomonas putida Candida tropicalis Candida maltose Rhizobium leguminosarum and Nocardia sp..
