Subject: Re: [AMBER] where to I get the parameters for Mg divalent ion

In my simulations I have been using the Mg representation from:

Oeschlaeger et al. Magnesium-cationic dummy atom molecules enhance
representation of DNA polymerase beta in molecular dynamics
simulations: improved accuracy in studies of structural features and
mutational effects. J Mol Biol. 2007 Feb 16;366(2):687-701. Epub 2006
Nov 3.

I have prepared frcmod and off files, available at:

You can use the leaprc.md6 in that archive with leap to load the parameters.

Hope that helps,
