Macrophomate synthase oxalacetate

Macrophomate synthase enzyme (MPHS), isolated from the fungus Macrophoma com-melinae, catalyzes the Diels-Alder cycloaddition between 2-pyrones 42 and decarboxylated oxalacetic acid 43 in aqueous buffered medium at pH 7.0, giving the benzoates 44 (Scheme 5.11). These types of aromatic compounds are commonlybiosynthesized by either a shiki-mate or polyketide pathway and therefore the reaction depicted in Scheme 5.11 supports the fact that the Diels-Alder reaction takes place in biosynthesis. [Pg.155]
