THE LOWEST TARGET FUNCTION STRUCTURE OF THIS FAMILY REMARK 3 WAS THEN SUBMITTED AS A PRE-FOLDED STRUCTURE IN CNS V. 1.0, AND REMARK 3 40 STRUCTURES CALCULATED UNDER COOL (< 288K) SIMULATED ANNEALING REMARK 3 AND CONJUGATE GRADIENT ENERGY MINIMIZATION. THESE CALCULATIONS REMARK 3 WERE CARRIED OUT IN THE PRESENCE OF EXPERIMNETAL NOE AND J- REMARK 3 COUPLING RESTRAINTS AS WELL AS ASSIGNED HYDROGEN BONDS REMARK 3 CONSISTENT WITH HX PROTECTION. DYANA 1.5: 799 UNIQUE NOE'S FROM REMARK 3 800 MHZ DATA, 444 RESULTING DISTANCE RESTRAINTS AFTER PSEUDOATOM REMARK 3 CALCULATION/REPLACEMENT AND REMOVAL OF NOE'S BETWEEN ATOMS REMARK 3 SEPARATED BY ONLY TWO OR THREE BONDS. 35 ALPHA-H TO AMIDE-H 3- REMARK 3 BOND J-COUPLING CONSTANTS AND 44 ALPHA-H TO BETA-H 3-BOND J- REMARK 3 COUPLING CONSTANTS FROM ECOSY DATA WERE ALSO INCLUDED. REMARK 3 DISULFIDES AND SEVEN HYDROGEN BONDS AS DETERMINIED FROM REMARK 3 SURROUNDING NOE'S AND HX DATA WERE INCLUDED AS PSEUDO-NOE REMARK 3 RESTRAINTS. CNS 1.0, PATCH LEVEL 0: 504 DISTANCE RESTRAINTS FROM REMARK 3 800 MHZ NOE DATA, CORRESPONDING TO THE SAME UPPER LIMIT REMARK 3 RESTRAINTS AS USED IN THE FINAL ROUND OF DYANA 1.5 CALULATIONS REMARK 3 (CONVERSION USING AQUA 2.0 IN PROCHECK_NMR, AND MODIFIED LOWER REMARK 3 LIMIT OF 1.6 ANGSTROMS WAS IMPOSED ON ALL NOE RESTRAINTS WHILE REMARK 3 KEEPING UPPER BOUNDS). DISULFIDE MAP WAS INCORPORATED INTO THE REMARK 3 COVALENT STRUCTURE OF THE MOLECULE AND THEREBY STRICTLY ENFORCED REMARK 3 IN THIS STEP. THE SEVEN HYDROGEN BONDS WERE INCLUDED IN A REMARK 3 SEPARATE RESTRAINT FILE. 34 ALPHA-H TO AMIDE-H 3-BOND J-COUPLING REMARK 3 CONSTANTS (NOT INCLUDING CYS-87 AMIDE MESUREMENT) WERE ALSO REMARK 3 INCLUDED. 40 STRUCTURES WERE SO CALCULATED AND ALL ARE DEPOSITED REMARK 3 HERE.
