TORSION ANGLE DYNAMICS FOLLOWED BY CARTESIAN MOLECULAR DYNAMICS IN EXPLICIT SOLVENT	The C-terminal residues 91-120 were disordered (as evidenced by 15N relaxation data) and were excluded from the model. INITIAL STRUCTURES WERE GENERATED USING THE CANDID MODULE OF CYANA. ADDITIONAL NOE ASSIGNMENTS WERE DETERMINED MANUALLY. PHI AND PSI TORSION ANGLE CONSTRAINTS WERE GENERATED FROM CHEMICAL SHIFT DATABASE SEARCHING USING THE PROGRAM TALOS (G. CORNILESCU).	XwinNMR
