NMR Refinement
Method	Details	Software
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	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.	VNMR

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	22 (minimized average structure)

Additional NMR Experimental Information
Details	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
