ID 1.1.3.42 DE prosolanapyrone-II oxidase. AN prosolanapyrone II oxidase/prosolanapyrone III cycloisomerase. AN Sol5. AN SPS. CA O2 + prosolanapyrone II = H2O2 + prosolanapyrone III. CC -!- The enzyme is involved in the biosynthesis of the phytotoxin CC solanapyrone by some fungi. CC -!- The bifunctional enzyme catalyzes the oxidation of prosolanapyrone II CC and the subsequent Diels Alder cycloisomerization of the product CC prosolanapyrone III to (-)-solanapyrone A (cf. EC 5.5.1.20). DR D7UQ40, SOL5_ALTSO ; //
