Publication Abstract from PubMed

Polyketides are a large family of pharmaceutically important natural products, and the structural modification of their scaffolds is significant for drug development. Herein, we report high-resolution X-ray crystal structures of the broadly selective acyltransferase (AT) from the splenocin polyketide synthase (SpnD-AT) in the apo form and in complex with benzylmalonyl and pentynylmalonyl extender unit mimics. These structures revealed the molecular basis for the stereoselectivity and substrate specificity of SpnD-AT, and enabled the engineering of the industrially important Ery-AT6 to broaden its substrate scope to include three new types of extender units.
