G6PD, immunoprecipitated from influenza infected or mock-infected cells and probed with anti-acetyl lysine antibody, showed a higher level of lysine residue acetylation in influenza virus-infected cells (**P < 0.001) (Figure 5A), thus indicating that G6PD was modulated by post-translational acetylation/deacetylation after influenza virus infection. The gene discussed is G6PD; the disease is influenza.
