NMR Refinement
Method	Details	Software
simulated annealing	The structures are based on the same restraints as previously used in the 1999 structure 1CG7, but different a-helix hydrogen bond restraints were included. These are the same as those used to calculate the structure of the complex with SRY_DNA.	XwinNMR

NMR Ensemble Information
Conformer Selection Criteria	structures with acceptable covalent geometry,structures with the lowest energy
Conformers Calculated Total Number	50
Conformers Submitted Total Number	20
Representative Model	1 (closest to the average,lowest energy)

Additional NMR Experimental Information
Details	This structure calculated using the same data as previously used in the 1999 structure 1CG7 but using new a-helix hydrogen bond restraints and XPLOR instead of DYANA.
