oxygenase

oxygenase
One of a group of enzymes (EC subclass 1.13) catalyzing direct incorporation of O2 into substrates; e.g., tryptophan 2,3-dioxygenase (tryptophan pyrrolase) catalyzing reaction between O2 and l-tryptophan to form N-l-formylkynurenine. Cf.:dioxygenase, monooxygenases.
- mixed function o. any monooxygenase that catalyzes AH + O2 + DH2 → AOH + H2O + D.
