Oxygenases catalyze the transference of oxygen from molecular oxygen to an oxidized substrate. They are a group of enzymes that form a class of oxydoreductases (enzymes that catalyze the transference of electrons from one molecule (called reductant) to another (the oxidant)). There are two classes of oxygenases: monooxygenases, which transfer an oxygen atom from molecular oxygen to the substrate and reduce the other atom to water, and dioxygenases, which are able to transfer both oxygen atoms to the substrate.
