Polyketide synthases

Type I polyketide synthases (PKSs) constitute a family of multi-domain enzymes and complexes that produce a vast array of structurally complex polyketides.  These natural compounds have antimicrobial, antifungal, antiviral, anticancer, and immunosuppressant activities and thus currently form the basis for nearly one third of paharmaceuticals. Our aim here is to study the structure and dynamics of PKSs in order to delineate the principles of natural product formation by these remarkable enzyme factories. These efforts are aiming to set the stage for bioengineering synthases that create novel complex molecules with improved pharmacological properties.
