Intradiol Dioxygenases — The Key Enzymes in Xenobiotics Degradation (original) (raw)

Intradiol dioxygenases play a critical role in the degradation of aromatic compounds, which are key processes in biogeochemical cycles and bioremediation efforts. These enzymes are grouped into three classes based on substrate specificity: catechol 1,2-dioxygenases, protocatechuate 3,4-dioxygenases, and hydroxyquinol 1,2-dioxygenases. They operate through a common mechanism that involves the cleavage of aromatic rings, linking their functions to environmental responses and potential applications in bioremediation technology.
