REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : PSEUDYANA REMARK 3 AUTHORS : CREMONINI REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURE CALCULATIONS WERE REMARK 3 PERFORMED ACCORDING TO A RECENTLY INTRODUCED TORSION ANGLE REMARK 3 DYNAMICS (TAD) APPROACH USING THE DYANA PROGRAM PACKAGE REMARK 3 (GUNTERT ET AL., 1996). PSEUDOCONTACT SHIFTS WERE INTRODUCED REMARK 3 AS CONSTRAINTS USING THE NEWLY DEVELOPED PSEUDYANA MODULE REMARK 3 (BANCI ET AL., 1997). THE OVERALL STRATEGY OF STRUCTURE REMARK 3 COMPUTATION COMPRISED THE FOLLOWING SUBSEQUENT STEPS:
