Figure 1From: Acetylation at K108 of the NS1 protein is important for the replication and virulence of influenza virusMass 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.Back to article page
