Abstract
Bacterial type I polyketide synthases (PKSs) are complex, multifunctional enzymes that synthesize structurally diverse and medicinally important natural products. Given their modular organization, the manipulation of type I PKSs holds tremendous promise for the generation of novel compounds that are not easily accessible by standard synthetic chemical approaches. In theory, hybrid polyketide synthetic pathways can be constructed through the rational recombination of catalytic domains or modules from a variety of PKS systems; however, the general success of this strategy has been elusive, largely due to a poor understanding of the interactions between catalytic domains, as well as PKS modules. Over the past several years, a fundamental knowledge of these issues, and others, has begun to emerge, offering refined strategies for the facile engineering of hybrid polyketide pathways.
