On the basis of these results, i tmay be suggested that the glycosylation site is located on the N-terminal serine of the peptide. However, it is well knownthat, on MALDI fragmentati on, ... [15,16]suggests that the peptides released from the PVX virions on mild trypsin hydrolysis correspond to the N-terminalregions of the PVX CP subunits. As can be seen in Fig. 3, the supernatant f...
