SummaryUnnatural combinations of polyketide synthase modules often fail to make a polyketide product. The causes of these failures are likely complex and are not yet amenable to rational correction. One possible explanation is the inability of the ketosynthase (KS) domain to extend the ketide donated to it by the upstream module. We therefore addressed the problem by exchanging KS domains of the acceptor module in a combinatorial fashion and coexpressing these chimeric modules with ketide-donor modules that naturally interact with the transplanted KS. This approach was remarkably successful in activating previously unproductive bimodular combinations, and the results augur well for the ongoing development of molecular tools to design and produce novel polyketides.
