WebWe discovered that biosynthesis of cylindrocyclophane F requires the use of two enzymes with unprecedented mechanisms. The first novel enzyme, called CylC, selectively chlorinates an unfunctionalized fatty acid using what is likely a diiron metal cofactor to activate an inert C–H bond. WebOur X-ray crystal structures reveal that CylK is a distinctive fusion of Ca2+-binding and β-propeller domains, and site-directed mutagenesis and anomalous diffraction with bound bromide ions locate the active site to the domain interface.
