I'm working with a viral protein that has been shown experimentally to interact with a host protein but the interaction is dependent on the viral protein being acetylated on 2 of its lysine residues. I have a 3D model of both the viral protein and the host protein, and I would like to dock them to recreate this interaction. Are there any web servers or software that I can use to simulate acetylation of the lysine residues on my viral protein so that I can use it in docking?
