[gmx-users] Simulation a labeled protein

[Faezeh Nami]

Dear all

I am trying to simulate a protein which a label  (a small organic molecule)
is covalently attached to a cysteine. Worth to say there is no label in the
original pdb file of protein and it was attached to the Cys. using a
software.
Should I insert the label parameters into the conf.gro file or I need to
modify a force field? If there is someone who has experiences in such
systems, please have some advice.

Thanks in advance,
Faezeh
