NMR Refinement
Method	Details	Software
simulated annealing	DISTANCE RESTRAINTS DERIVED FROM THE CYANA CALCULATIONS, TORSION ANGLE RESTRAINTS DERIVED FROM TALOS BASED ON SECONDARY CHEMICAL SHIFTS, AND RDC RESTRAINTS WERE APPLIED FOR A WATER REFINEMENT CALCULATION USING A SIMULATED ANNEALING PROTOCOL IN CNS. THE ZINC COORDINATION GEOMETRY WAS DEFINED AND MAINTAINED BY DISTANCE AND ANGLE CONSTRAINTS. .	CNS-ARIA

NMR Ensemble Information
Conformer Selection Criteria	LOWEST ENERGY
Conformers Calculated Total Number	100
Conformers Submitted Total Number	20
Representative Model	1 (n/a)

Additional NMR Experimental Information
Details	THE CHEMICAL SHIFTS OF THE DEAF-1 MYND DOMAIN WERE ASSIGNED USING STANDARD HETERONUCLEAR EXPERIMENTS ACQUIRED AT 295 K ON A 1 MM UNIFORMLY 15N,13C LABELED SAMPLE. EXPERIMENTS WERE CARRIED OUT ON BRUKER SPECTROMETERS OPERATING AT A PROTON FREQUENCY BETWEEN 500 AND 900 MHZ. ALL SPECTRA WERE PROCESSED USING THE PACKAGE NMRPIPE- NMRDRAW
