The nucleotide and predicted amino acid sequences have been obtained for the fusion (F) protein gene of the avirulent strain La Sota of Newcastle disease virus (NDV). The F1 N-terminus begins with the tripeptide Leu-Ileu-Gly instead of Phe-X-Gly as usually observed in fusion peptide. It was found that the cleavage-activation domain of the avirulent La Sota strain contained single (but no pairs of) basic residues in the sequence Gly-Arg-Gln-Gly-Arg. Hydrophobicity analysis suggested that the cleavage-activation domain became more hydrophobic and could be less accessible for host-specific protease(s); dibasic residues next to the F1 N-terminus were shown to be important for keeping the cleavage-activation site in exposed positioning, suitable for F protein activation. Comparative sequence analysis of the NDV F proteins revealed a striking homology between lentogenic La Sota and mesogenic Beaudette C strains. Furthermore, 58 variable positions were recorded in the NDV F protein, excluding signal sequence; some of these mutations, in the cysteine-clustered region, were surmised to alter virulence.
