Re: [gmx-users] Forcefield parameters for Zinc
Hi, Related to the Zn-parameters; where can I find the reference (author, journal, year) to the sigma and epsilon (1.95998e-01 5.23000e-02) parameters that I find in /gromacs/top/amber99sb.ff/ffnonbonded.itp for [ atomtypes ] Zn. I would like to use amber99sb force field in my Gromacs simulation of a Zn- containing protein.

I hope it helps, Leandro. Hi Leandro, thanks for your reply. I did not expect the parameters for Zn in Amber99sb to work directly (I was thinking of adding distance restraints on Zn-His interaction). However in a short equilibration the parameters did work and the Zn stayed in the protein as it should. So I would like to know more about the work behind these LJ sigma and epsilon parameters and how the were chosen and evaluated. Does anyone know where I find the reference to the LJ sigma and epsilon parameters that I find in /gromacs/top/amber99sb.ff/ffnonbonded.itp for [atomtypes ] Zn?

Re: [gmx-users] Forcefield parameters for Zinc and phosphorylated residues
Hi, QM parameterisation is how people tend to have done it for things like copper-bound proteins with GROMOS. I have been recently simulating one of these copper-bound proteins using a GROMOS force field (and indeed an AMBER force field too). I can send you a couple of papers regarding the GROMOS parameterisation for this protein off list if you like, so you can at least see their parameterisation methods for the copper centre?
