Abstract

Modularity is a highly sought after feature in engineering design. A modular catalyst is a multi-component system whose parts can be predictably interchanged for functional flexibility and variety. Over the past two decades, much of the research in our laboratory has focused on understanding the modularity of a class of multifunctional enzymes called polyketide synthases (PKSs). PKSs catalyze the biosynthesis of a broad range of complex natural products in microorganisms, including many well-known and emerging antibiotics. A better understanding of the fundamental principles governing their modular chemistry promises to create powerful opportunities for engineering new medicines, and may even open the door to radically new catalytic processes for functionally dense, chiral synthons. © 2009 American Institute of Chemical Engineers AIChE J, 2009
