MethodDetailsSoftware
simulated annealingThe structures are based on a total of 1492 restraints (1281 NOE-derived distance restraints, 182 dihedral angle restraints and 29 hydrogen bond restraints). The structures were also refined in water using XPLOR-NIH 2.9.6 using the protocol of Linge et al. (Linge, J. P., Williams, M. A., Spronk, C. A., Bonvin, A. M., & Nilges, M. ,2003.
