Method TORSION ANGLE DYNAMICS SIMULATED ANNEALING
Details 20 CONFORMERS COMPATIBLE WITH THE NMR CONSTRAINTS WERE CALCULATED USING DYANA 1.5 AND THE STANDARD TORSION ANGLE SIMULATED ANHEALING PROTOCOL. PRELIMINARY CALCULATIONS WERE CARRIED OUT INDEPENDENTLY FOR EACH OF THE TWO N- AND C- TERMINAL DOMAINS OF THE PROTEIN. INITIALLY ONLY NOE DISTANCE CONSTRAINTS WERE IMPOSED. THE INITIAL STRUCTURES WERE THEN USED TO ASSES THE ACCURACY OF THE TORSION ANGLE CONSTRAINTS GENERATED BY ANALYSIS OF HA, CA, CB, CO AND N CHEMICAL SHIFTS WITH THE PROGRAM TALOS. FINALLY, UPPER AND LOWER LIMIT DISTANCE CONSTRAINTS WERE IMPOSED FOR UNAMBIGUOUS INTRAHELICAL H-BONDS.
