Mass spectrometry analysis of the acetylation modification at K108 of the NS1 protein of WSN-wt. One acetylation modification was found at one y3 peak on lysine, which is in the amino acid sequence HWFMLMPKQK of the WSN NS1 protein. The MS/MS spectra obtained with HCD of the + 3 m/z ion at 1021.8967 are shown.
