A mutant generated by expression of an engineered DEBS 1 protein from the erythromycin-producing polyketide synthase (PKS) in Streptomyces coelicolor produces the triketide as a lactone, but the major product is the nor-analogue derived from acetate as starter acid

Compounds and methods useful for the synthesis of (+)-discodermolide, a naturally occurring microtubule stabilizing agent useful as an anti-cancer agent.
Combinatorial libraries of polyketides can be obtained by suitable manipulation of a host modular polyketide synthase gene cluster such as that which encodes the PKS for erythromycin. The combinatorial library is useful as a source of pharmaceutically active compounds.
