Modular Oxime formation: collaboration with J. Piel group published

Benzolactone enamides, a number of which incorporate a methylated oxime moiety, are produced by a range of organisms, and constitute a family of cytotoxic natural products. Here, we determine how this capped oxime group is installed during assembly of the model polyketide lobatamide by a modular trans-AT polyketide synthase and provide molecular insight into the responsible mono-oxygenase domain by X-ray crystallography.
