[gmx-users] How to use deprotonated Cys

[Alpay Temiz]

Copy your forcefield rtp file to you working diecrtory and comment out the
CYSH entry

This way pdb2gmx will use CYS (deprotanated) topology,
It may give a warning as cant find CYSH trying to use CYS

Give it a try

Hi all,
I have protein with cys in active site, and I want to use deprotonated
cys. In manual for pdb2gmx  clearly says on option of choosing Cys
protonated state possibility but why that option not appearing while
running pdb2gmx , just like for Arg, His, Asp and Glu. I read
quite a lot of mails regarding this issue most of them are in 2004
archives. Hope things are now changed and I can get some direct
solution for this from any of you. 
With thanks!
