Method	Details	Software
simulated annealing	The structures are based on a total of 3035 restraints. 102 are from alpha-helical hydrogen bond restraints within the protein (2/h-bond). 76 are hydrogen bond restraints for Watson-Crick base pairs in the DNA. The rest are NOE-derived. 2197 of the NOE restraints are protein-protein restraints, 578 are DNA-DNA restraints, and 82 are protein-DNA restraints.	XwinNMR
