Very Important Paper: Evaluating Ketoreductase Exchanges as a Means of Rationally Altering Polyketide Stereochemistry

Thibault Annaval, Cédric Paris, Peter F. Leadlay, Christophe Jacob,* Kira J. Weissman*

Reduced polyketide secondary metabolites exhibit a wide range of useful biological properties, including antibiotic and anti-cancer activities. There is great interest in precisely tailoring these structures in order to optimize their pharmaceutical properties. One strategy to create analogues is by genetic engineering of the underlying biosynthetic machinery, the polyketide synthases (PKSs). PKSs are modular multienzymes composed of repeated sets of catalytic and carrier protein domains, each of which performs a specific task in the biosynthesis. Now, a team lead by C. Jacob and K. J. Weissman (Université de Lorraine, France) have identified the first ketoreductase domains which, when introduced into a model PKS, allow for the efficient alteration of the stereochemistry of a methyl group on the corresponding product.

    A mono- and diglyceride lipase was engineered to a triacylglyceride lipase by introducing a single point mutation (Q282L). The variant has broad substrate specificity on triacylglycerides. The results indicate that the main reason that the wild-type enzyme does not accept triacylglycerides is not their bulkiness, but specific hydrophobic interactions.
