Comparison of current and previous structures of the tropomyosin overlap complex. A) The structure of chicken smooth muscle GP7-TmC:TmN-EB1 determined here. B) Rat non-muscle tropomyosin complex model determined by NMR. C) Rat skeletal tropomyosin complex solved by NMR. D) X-ray crystal structure of rabbit skeletal tropomyosin. Panel B was prepared from the coordinates supplied in the supporting information of reference (28). Panels C and D were prepared from PDB files with the accession numbers 2G9J and 2Z5I (27–29). Note; the free N-terminal chain in the X-ray structure of rabbit skeletal tropomyosin interacts with a crystallographically related C-terminal coiled coil, which doubtless stabilizes this arrangement.
