Regulation and manipulation of the gene clusters encoding type-I PKSs
2000
Modular polyketide synthases are large, multifunctional enzyme complexes that are involved in the biosynthesis of important polyketides. Recent studies have revolutionized our understanding of the linear organization of polyketide-synthase-gene clusters. They have provided crucial information on the initiation, elongation and termination of polyketide chains, and thus a rational basis for the generation of novel compounds. Combinatorial libraries have helped this field to move from a random approach to a more empirical phase. The large number of diverse analogs of antibiotics that are presently produced demonstrate the enormous potential of combinatorial biosynthesis.
