[Oligopeptides of the nucleocapsid proteins of influenza A viruses]

The method of oligopeptide mapping has shown the presence of similar oligopeptides in nucleocapsid proteins of various influenza viruses, and at the same time diverse oligopeptides in different viruses. This indicates shifts in the sequences of aminoacid residues in various influenza viruses. Various oligopeptide composition of nucleoprotein is marked not only in the viruses with shift hemagglutinin differences (H1 and H3), but also in the drift-variants of viruses (H0-H1).
