NMR Refinement
Method distance geometry/simulated annealing
Details The structures were generated by 4-dimensional simulated annealing (4D-SA) with program EMBOSS, based on a total of 1341 experimental restraints, 901 and 356 are the NOE derived distance restraints for protein and DNA, respectively, 29 are protein dihedral restraints and 55 are protein-DNA intermolecular restrainTs. In addition, 66 hydrogen bond and 221 ring-to-ring restraints are applied through 4D-SA to maintain the DNA base pair planarity.
