- prosolanapiron II + O2 prosolanapiron III +H2O2
Ovaj enzim učestvuje u biosintezi fitotoksina solanapirona u nekim gljivama. On je bifunkcionalani enzim koji katalizuje oksidaciju prozolanapirona II i naknadnu Diels Alderovu cikloizomerizaciju produkta prozolanapirona III do (-)-solanapirona A (cf. EC 5.5.1.20, prozolanapiron III cikloizomeraza).
