Re: [gmx-users] CG-MD to study the conformational changes of proteins...
Dear Gromacs Users, I have a insilico model of Mycobacterium cell wall (surface) protein which has no transmembrane helices.Which Gromacs tutorials should I follow for MD studies to know about its conformational stability and latter for protein - ligand studies.

Re: [gmx-users] CG-MD to study the conformational changes of proteins...
Hi Quyen, Although Martini is a good CG force field for a system contains lipids and proteins, it still needs some improvements to capture conformational changes (especially large changes). Is there any hybrid model available (and ready to use) for such a system? Regards, Dariush On Mon, Dec 26, 2016 at 11:23 AM, Quyen V.

Re: [gmx-users] CG-MD to study the conformational changes of proteins...
Nikhil say: I would like to study the conformational study of proteins (Amyloid beta) in presence of lipid bilayers and other molecules. Can anyone tell me the possibility of Coarse-grained molecular dynamics for this study, since all-atom MD need more time and my system contains more atoms, so I'm thinking to go for CGMD. in CG-MD can we do the same analysis as in All-atom MD.? You need to find a force field that support for protein coarse-grain model such as Martini: http://cgmartini.nl/ to save simulation time you can you CG model or hybrid model( result better than CG model because a important region is treated as standard MD, less important region is use CG model -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?

[gmx-users] CG MD Simulation of DNA and PAMAM dendrimers
Dear GROMACS users: I want to study the complexation between PAMAM dendrimer and DNA using coarse-graining molecular dynamics simualtions (MARTINI force field) utilizing GROMACS version 5.0.3. MD integrator is used with time step of 20 fs, but I could not run the simulation with this time step, I got *segmentation fault. *Sure before running long simulation I minimized the system. I attached the .mdp file that I use. Could you please help me? Waiting your response. Thank you.
