RESUMO

Nucleotide sequences of around 200 residues were determined adjacent to the 3' terminus of the genome RNA of vesicular stomatitis virus, New Jersey serotype, and adjacent to the 3'-terminal polyadenylic acid tract of the N protein mRNA of the same virus. These sequences were compared with the corresponding sequences previously determined for the Indiana serotype of vesicular stomatitis virus. The sequences obtained for the two strains were readily aligned, showing 70.8% homology overall. Examination of the sequences allowed identification of the translation initiation and termination codons for the N mRNA of each serotype. The deduced N-terminal and C-terminal amino acid sequences of the two N polypeptides were each similar, and most of the differences between them consisted of substitution by a clearly homologous amino acid. It was proposed that these nucleotide sequences, within limits imposed by their functions, comprise reasonably representative measures of the extent of sequence homology between the genomes of the two serotypes, and that this is higher than previously estimated, but with little exact homology over extended regions.
