[Synthesis, cloning and determination of the primary structure of a full-size DNA copy of the neuraminidase gene from influenza virus type A subtype H1N1].

Complete nucleotide sequence of the cloned full-length DNA copy of the influenza virus A (H1N1) neuraminidase gene has been determined. The predicted amino acid sequence is compared with sequences of neuraminidases from other influenza virus strains. A section of the neuraminidase is found to be homologous to the chicken lysozyme catalytic centre.
