Details The model with the best correlation coefficient was selected by ADP_EM from a pool of 10000 models generated by RRT_SAMPLE using rigid bodies derived from 2R09 (autoinhibited core, amino acids 63-399) and a canonical antiparallel coiled coil (amino acids 18-53) built with CCBuilder. Flexible regions with reasonable geometry were modeled with MODELLER.
