Dear Gromacs Users I want to simulate human p53 protein and two of its mutants to see how mutation affect its structural properties. I obtained the nature and mutant pdb files form protein data bank. when I submitted the mutant files to pdb2gmx command it gave error on misiing atoms. I fixed the

See following paper for modelling of initial steps of glycation process protein: http://www.tandfonline.com/doi/abs/10.1080/07391102.2010.10507354#preview For study of advanced glycation end processes, there is nothing to do with emperical FF, you need to use QC approches; see following papers fo

Hi Ahmet, Nothing wrong with specbond at this point. The bonds are correctly added, and apparently the bondtypes are read correctly too, because grompp only starts complaining at the point of angles. Check the atomtypes corresponding to the atoms involved in those angles in the .itp file that is g
