Hypothemycin is a macrolide protein kinase inhibitor from the fungus Hypomyces subiculosus. During biosynthesis, its carbon framework is assembled by two iterative polyketide synthases (PKSs), Hpm8 (highly reducing) and Hpm3 (nonreducing). These were heterologously expressed in Saccharomyces cerevisiae BJ5464-NpgA, purified to near homogeneity, and reconstituted in vitro to produce (6'S,10'S)-trans-7'
