Abstract:
:Polyketides are a large class of structurally diverse, biologically active natural products. Recent experiments add evidence that many of the enzymes involved in the biosynthesis of these natural products are intrinsically tolerant of nonnatural substrates. In addition, an increasing understanding of structure-function relationships in various enzyme-substrate systems is aiding efforts to begin engineering these proteins for even greater synthetic utility.
