To study proteins in membranes just add our parameters to the AMBER protein force field you would like to use. They are supposed to work with AMBER99SB/AMBER99SB-ILDN/AMBER03/GAFF FF for proteins and small molecules.Ĭannot find the lipid bilayer composition you are looking for? Go over to MemGen or CHARMM-GUI and use their interface to built your system. Parameters are available for saturated and unsaturated PC, PS, PE, PG, SM lipids and cholesterol. Here we share Slipids force field parameters inįormat, ready to use as well as equilibrated lipid bilayers.
