Abstract
Nuclear magnetic resonance spectroscopy is used routinely for studying the three-dimensional structures and dynamics of proteins. Structure determination is usually done by adding restraints based upon NMR data to a classical energy function and performing restrained molecular simulations. Here we report on the implementation of a script to extract NMR restraints from a NMR-STAR file and export it to the GROMACS software. With this package, it is possible to model distance restraints, dihedral restraints, and orientation restraints. The output from the script is validated by performing simulations with and without restraints, including the ab initio refinement of one peptide.
