abstract：:We have carried out an exhaustive search for amino acid sequence similarities between vesicular stomatitis virus (VSV) proteins and database entries. Unexpectedly, we found that the L polymerase protein contains two blocks of sequence (residues 725-1102 and 1291-1671) with distant but statistically significant similar...
