    Refinement
    Method THE NMR STRUCTURE CALCULATION PROGRAM USED DYANA THAT USES SIMULATED ANNEALING COMBINED WITH MOLECULAR DYNAMICS IN TORSION ANGLE SPACE (TORSION ANGLE DYNAMICS)
    Details INTENSITIES OF DIPOLAR CONNECTIVITIES IN 3D NOESY-HSQC, 3D HNHA AND 2D NOESY WERE MEASURED WITH THE INTEGRATION ROUTINES OF THE PROGRAM XEASY. PEAK VOLUMES WERE CONVERTED INTO UPPER DISTANCE LIMITS BY FOLLOWING THE METHODOLOGY OF THE PROGRAM CALIBA. 3JHNHA COUPLING CONSTANTS WERE OBTAINED FROM THE RATIO BETWEEN THE INTENSITY OF THE DIAGONAL PEAK AND THAT OF THE CROSS PEAK OF THE 3D HNHA EXPERIMENT. THE 3D STRUCTURE WAS CALCULATED WITH THE PROGRAM DYANA; THE FINAL DYANA FAMILY WAS FORMED BY THE 36 CONFORMERS WITH THE LOWEST TARGET FUNCTION. REFINEMENT WAS PERFORMED THROUGH RESTRAINED ENERGY MINIMIZATION WITH THE SANDER MODULE OF THE PROGRAM AMBER. NOESY CROSS PEAKS WERE BACK -CALCULATED ON THE FINAL STRUCTURE WITH THE PROGRAM CORMA.
