摘要

Abstract Macrophomate synthase from the fungusMacrophoma commelinae IFO 9570 is a Mg (II)-dependent dimeric enzyme that catalyzes an extraordinary, complex five-step chemical transformation from 2-pyrone and oxalacetate to benzoate involving decarboxylation, C–C bond formation, and dehydration. The catalytic mechanism of the whole pathway was investigated in three separate chemical steps. In the first ...
