[gmx-users] Query regarding protonation and deprotonation of some residues

[sonali dhindwal]

Thanks Kass for the help.

I want to specifically protonate one of the lysine near the active site and deprotonate Tyr and Ser. It will be kind if  you can please help me to know how to select that specific residue number.

Regards

  Hi,

    

    You need to define the protonation sate vie pdb2gmx.

    

    pdb2gmx -tyr -lys

            Hello All,

              

              I came through this research article, in which author has
              selectively deprotonated and protonated some of the
              residues to
              simulate the condition for electrostatic interaction with
              the substrate while carrying out molecular dynamics
              simulation.

              

              It will be appreciable, if
              you could help me regarding the same, how to deprotonate
              Tyr
              and Ser residue and protonate Lysine residue of the
              protein while
              preparing the protein topology to be used for molecular
              dynamics simulation in Gromacs.

              

              Thanks and Regards.
