Beside pH and temperature, are there any other factors effect on the activity of xanthine oxidase such as light, concentration or any else? Please give me some suggests and more details. Thanks so much!
Hello!
Oxygen levels will have an effect on xanthine oxidase activity. As more oxygen is added to the system, superoxide rather than hydrogen peroxide is produced.

All the best!
Coimmobilization of xanthine oxidase with superoxide dismutase and catalase improved the operational stability, suggesting that O2− and H2O2 side-products of the enzymatic reaction were involved in the inactivation. Coimmobilization with albumin also had some stabilizing effect.
