WebMay 6, 2000 · Cylindrocyclophane Biosynthesis Involves Functionalization of an Unactivated Carbon Center. Journal of the American Chemical … 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.
