The COVID19 pandemic has resulted in massive pain and distress to all aspects of human life. A key viral element for effective infection is the surface protein, spike (the Corona), which has been a major target for drug development against the virus. Using multimicrosecond simulations with NAMD and analyzed with VMD, we show that glycosylations of the spike, which are known to shield the protein from most antibodies, also equip the protein with a larger range of motion, thus making it more effective in search of human receptors.
