Gcmc water silica

WebIn this work, we applied GCMC in 21 protein-ligand systems to assess the performance of GCMC for rehydrating buried water sites. While our results show that GCMC can rapidly rehydrate all selected water sites for most systems, it fails in 5 systems. In most failed systems, we observe protein/ligand motions, which occur in the absence of water ... WebThe adsorption properties of water adsorbed on various silica substrates are investigated by way of Grand Canonical Monte Carlo simulations (GCMC).
