[gmx-users] Can I delete Mn^2+ ion from a protein molecule and then run MD?

[Hu Zhongqiao]

Dear All,
I want to do MD for a protein crystal containing Mn^2+ ion. Because
gromacs has not provided the force field for Mn^2+ ion, I want simply
delete Mn ion and then run MD. Will this lead any consequences making
the MD results unacceptable?  If so, what else should I do instead?
