Method ALL CALCULATIONS WERE PERFORMED USING X-PLOR V3.8 WITH SCRIPTS FROM THE X-PLOR 3.1 MANUAL A. A. BRUNGER (1992), NEW HAVEN: YALE UNIVERSITY PRESS ACCORDING TO THE METHOD DESCRIBED BY M. NILGES, G. M. CLORE & A. M. GRONENBORN
Details A TOTAL OF 1510 NOE DERIVED DISTANCE RESTRAINTS THAT COMPRISE 700 INTRARESIDUE, 332 SEQUENTIAL, 83 SHORT RANGE (1<|I-J|<=4), 394 LONG RANGE (|I-J|>4) WERE INCLUDED.. 1 DISULPHIDE BOND DISTANCE RESTRAINT, 86 HYDROGEN BOND RESTRAINTS, 53 PHI ANGLE RESTRAINTS, 70 PSI ANGLE RESTRAINTS, AND 48 CHI1 RESTRAINTS WERE ALSO INCLUDED.
NMR Ensemble Information
Conformer Selection Criteria STRUCTURES WITH ACCEPTABLE COVALENT GEOMETRY,STRUCTURES WITH THE LEAST RESTRAINT VIOLATIONS,STRUCTURES WITH THE LOWEST ENERGY
Conformers Calculated Total Number 60
Conformers Submitted Total Number 22
Representative Model Choice Rationale
1 minimized average structure
Additional NMR Experimental Information
1 CBDN2 WAS STUDIED IN THE PRESENCE OF SATURATING CONCENTRATIONS OF CELLOPENTAOSE. HOWEVER, DUE TO SPECTRAL OVERLAP, THE OLIGOSACCHARIDE WAS NOT INCLUDED IN THE STRUCTURE CALCULATIONS
