Fluorine-NMR studies of chimpanzee hemoglobin.
It has been demonstrated that 4-fluorophenylalanine, a known inhibitor of protein synthesis, becomes incorporated into hemoglobin when present in the diet of a chimpanzee. 19F-NMR spectra of various forms of this protein show well-resolved lines, each line presumably corresponding to a unique phenylalanine/fluorophenylalanine position of the primary sequence. Fluorine chemical shifts and, by implication, tertiary structures vary with the oxidation state and ligand.
