[gmx-users] deprotonated HIS in AMBER03 force field

[Yuno Lee]

Hi all,
I'm simulating with zinc finger protein NMR structure (PDB ID: 2JUN).

In this protein, only deprotonated HIS and CYS are placed with zinc ions.

So, we tried with AMBER03 force field which has deprotonated CYS as CYM.

But I couldn't find about deprotonated HIS in ffamber03.rtp file.


Could anyone plz tell me how to use deprotonated HIS?


Thank you all
