Amino acid sequence of the Pronase-released heads of neuraminidase subtype N2 from the Asian strain A/Tokyo/3/67 of influenza virus.
The amino acid sequence of the Pronase-released heads of neuraminidase subtype N2 from the A/Tokyo/3/67 strain of influenza virus was determined by a combination of peptide and nucleic acid sequence analysis. The results show that the Pronase-released heads contain 396 amino acid residues and extend from residue 74 in the original protein to the C-terminus at residue 469. The heads contain five potential glycosylation sites at asparagine residues 86, 146, 200, 234 and 402, but only the first four are glycosylated. The sequence homology with the corresponding region of the previously published sequence of the neuraminidase subtype N1 [Fields, Winter & Brownlee (1981) Nature (London) 290, 213-217] is 45%. Detailed evidence for the sequence data has been deposited as Supplementary Publication SUP 50116 (14 pages) at the British Library Lending Division, Boston Spa, Wetherby, West Yorkshire LS23 7BQ, U.K., from whom copies may be obtained on the terms given in Biochem.
