to Vienna-PTM, a resource for exploring protein post-translational modifications (PTMs) using molecular dynamics (MD) simulations! Here, you can modify a protein PDB file of your choice with one or more supported PTMs and obtain force field parameters (GROMOS 45A3, 54A7 [ref] and 54A8 [ref]) and input files needed to perform MD simulations of the modified proteins using the GROMACS package [ref]. Currently, we support a total of 260 different enzymatic and non-enzymatic modifications.
