| simulated annealing | This ensemble of the structures were re-refined with NMR-derived restraints. The original refinements have been published in JMB (2005, 351(2), pp351-82). We re-refined the structures of the tetraloop-receptor RNA/RNA complex using the restraint files whose formats are consistent with Xplor-nih. No SAXS data was used in this refinement. | X-PLOR NIH |
