REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : NULL REMARK 3 AUTHORS : NULL REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: REMARK 3 THE 3D STRUCTURE OF THE PH 4.75 FORM OF THE ASCARIS TRYPSIN REMARK 3 INHIBITOR IN SOLUTION BY NMR IS BASED ON 1078 EXPERIMENTAL REMARK 3 RESTRAINTS COMPRISING: 43 SHORT RANGE (1 < |I-J| <=5) AND REMARK 3 218 LONG RANGE (|I-J|>5) INTERRESIDUE INTERPROTON REMARK 3 DISTANCE RESTRAINTS, 320 INTRARESIDUE INTERPROTON DISTANCE REMARK 3 RESTRAINTS, 48 DISTANCE RESTRAINTS FOR 4 HYDROGEN BONDS, REMARK 3 AND 59 PHI, 49 PSI AND 41 CHI1 TORSION ANGLE RESTRAINTS. A REMARK 3 COMPLETE LIST OF EXPERIMENTAL RESTRAINTS HAS BEEN REMARK 3 DEPOSITED WITH THE BROOKHAVEN DATA BANK. REMARK 3 REMARK 3 THE STRUCTURES ARE CALCULATED USING THE HYBRID METRIC REMARK 3 MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING REMARK 3 METHOD DESCRIBED BY: NILGES, M., CLORE, G.M. & REMARK 3 GRONENBORN, A.M. (1988) FEBS LETT 29, 317-324 ALL REMARK 3 STRUCTURAL STATISTICS ARE GIVEN IN REFERENCE 1. REMARK 3 REMARK 3 THIS ENTRY PRESENTS THE RESTRAINED MINIMIZED AVERAGE REMARK 3 STRUCTURE (SA)R. THIS IS OBTAINED BY FIRST AVERAGING THE REMARK 3 COORDINATES OF THE INDIVIDUAL 32 DYNAMICAL SIMULATED REMARK 3 ANNEALING SA STRUCTURES BEST FITTED TO RESIDUES 5 - 60, AND REMARK 3 SUBJECTING THE RESULTING COORDINATES TO RESTRAINED REMARK 3 MINIMIZATION. COLUMNS 61 - 66 IN THIS SET OF COORDINATES REMARK 3 (THE B VALUE FIELD IN X-RAY STRUCTURES) GIVES THE AVERAGE REMARK 3 RMS DIFFERENCE BETWEEN THE INDIVIDUAL SA STRUCTURES AND THE REMARK 3 MEAN STRUCTURE. THE QUANTITIES IN THIS FIELD OF THE REMARK 3 INDIVIDUAL STRUCTURES HAVE NO MEANING. THE INDIVIDUAL REMARK 3 STRUCTURES ARE PRESENTED IN PROTEIN DATA BANK ENTRY 1ATD.
