Phytopathogenic fungus Macrophoma commelina

The phytopathogenic fungus, Macrophoma commelinae has the ability to transform 2-pyrone 146 into the corresponding benzoate analog macrophomate (152) (Scheme 27). This complex aromatic conversion is catalyzed by a single enzyme, with oxalacetate as a substrate for the C3-unit precursor. MPS is a... 

The first determined structure of a Diels-Alderase was that of the macrophomate-synthase of the phytopathogenic fungus Macrophoma commelinae (Fig. 5.158).
