Catalase has an ability to convert solar radiation into reactive oxidant species (ROS). It is involved in regulation of tissue peroxide levels.
Mutation in catalase gene result in the progress of essential hypertension (EH).
Catalase catalyzes the degradation of hydrogen peroxide into water and oxygen. It can also react with alkylhydrogen peroxides, such as methylperoxide and ethylperoxide and the second H2O2 molecule can be replaced by methanol, ethanol, propanol, formate and nitrate as a hydrogen donor.
