Electric fields in biomolecular systems using the AMOEBA polarizable force field
Description | Through this award we have explored the accuracy of a popular polarisable force field widely used in the biomolecular simulation community. We have found that it is able to reproduce hydration and solvation free energies with an accuracy broadly consistent with conventional fixed-charge force fields, but at significantly greater cost. This is disappointing, but perhaps unsurprising given the time that has been spent in optimising conventional fixed-charge models. More interestingly, however, we have also shown that the AMOEBA polarisable force field is able to reproduce the electric fields in proteins with an accuracy comparable to density functional theory, but at a fraction of the cost. Thus if electrostatics are particularly important, the polarisable force field represents a significant improvement over fixed charge models. |
Exploitation Route | These data support the use of polarisable force fields in modelling protein electrostatics. This will likely be relevant to workers seeking to understand enzyme structure and function |
