Abstract: | Correlation of tropomyosin amino acid sequence with uranyl acetate stained magnesium salt tactoids has been carried out by a computer graphic technique. Contrary to some previous suggestions, the results seem to indicate that there is no chain stagger within the molecule and the molecules are aligned with 178 ± 2 residue overlap in antiparallel array. In addition, the molecules for one particular tactoid appear to have an end overlap of approximately 21 residues. |
