Crystal structure and molecular interactions of tropomyosin.
The three-dimensional structure of tropomyosin filaments has been determined by X-ray crystallography. The ends of the molecules were located by reference to the single pair of cysteine residues. Departures from the alpha-helical-coiled coil conformation may occur in localised domains along the molecule as well as at the overlapping ends.
