Summary
The amino acid sequences of four strains of tobacco mosaic virus isolated in different parts of the world are compared. The differences between the strains are discussed with respect to special proteinchemical features (such as beginning of the chain, deletion of amino acids, number of different amino acids, sizes and distribution of regions with invariable amino acids) and with respect to the possibility of deducing the most probable nucleotide sequence for the coat protein cistron of tobacco mosaic virus.
The complete amino acid sequences of the two RNA bacteriophage strains fr and f2 are compared. According to their coat proteins three groups of phages can be formed: 1) MS 2, f2 M 12 and R 17, 2) fr and 3) Qβ.
