Catalases are antioxidant enzymes that catalyse the conversion of hydrogen peroxide to water and molecular oxygen, serving to protect cells from its toxic effects. Most catalases are monofunctional, haem-containing enzymes, although there are also bifunctional haem-containing peroxidase/catalases that are closely related to plant peroxidases, and non-haem, manganese-containing catalases that are found in bacteria [1].
Allergenic catalases were described in several fungal species [2, 3].
