The systems described above were briefly minimized and equilibrated using NAMD 2.14 to eliminate bad contacts. Simulations were performed in NAMD 3.0a9 explicit solvent and CHARMM36 carbohydrate, lipid, and protein force fields. In keeping with CHARMM standard, a 12Å cutoff was used, together with the TIP3 water model. Long range electrostatics was handled using the particle mesh Ewald method with 1.2Å grid spacing. The system was simulated in an NPT ensemble using a Langevin thermostat and barostat. To enable 2fs timesteps, we used the SETTLE algorithm to fix hydrogen bond lengths. Unless otherwise stated, systems were simulated to a length of 1 µs.
