... for the function of NS1 protein in the infected cells [7,10,16-18]. Our knowledge about the existence of these motifs in the NS gene pool of influenza A viruses in their natural reservoirs is insufficient. ... variation in the NS gene pool of influenza A viruses in their natural reservoirs in Europe is incomplete. In this study we determined the subtypes...

... the amino terminus of the pro- tein. Using this method, we showed that asparagine 26 represents the amino terminus of P40. Knowing, that the first amino acids of the processed P40 and P90 is the ... N-terminus instead of a free amino group [32]. Therefore, the asparagine in position 26 was labeled within the intact protein at its a-amino group and represents the ami...
