[gmx-users] simulation with ligand at the active site

2011-04-27 Thread onetwo
Hello Users, I have a query regarding simulation with the ligand. In my protein there are two ligands, one of them (coenzyme) is from the crystal data, and other I have docked at the active site, while docking it is showing good interaction with all the active site residues very well. I used

Hello All, I want to know one thing that if MD could be used in my case, i have a protein for which crystal structure is known with a conenzyme bound to it. It is given in literature that related proteins of this family shows large conformational change near the substrate binding region when
