Details THE STRUCTURES ARE BASED ON A TOTAL OF 665 CONFORMATIONALLY-RESTRICTING NOE-DERIVED DISTANCE RESTRAINTS, 73 DIHEDRAL ANGLE RESTRAINTS, AND 44 HYDROGEN BOND RESTRAINTS (10.0 RESTRAINTS PER RESIDUE FOR RESIDUES 4-90, EXCLUDING LOOP RESIDUES 51-59). THE 20 RESIDUE N-TERMINAL TAG (MGSSHHHHHHSSGLVPRGSH) WAS NOT INCLUDED IN THE STRUCTURE CALCULATION AND IS NOT PRESENT IN THE COORDINATES.

Conformer Selection Criteria all calculated structures submitted
Conformers Calculated Total Number 20
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 combination of low energy, close to average, and few violations
Additional NMR Experimental Information
1 BACKBONE AND SIDECHAIN ASSIGNMENTS WERE DETERMINED MANUALLY FROM TRIPLE-RESONANCE NMR DATA. NOE DISTANCE RESTRAINTS WERE DERIVED MANUALLY FROM NOESY DATA. PHI DIHEDRAL ANGLE RESTRAINTS WERE DERIVED FROM THE HNHA EXPERIMENT. PSI DIHEDRAL ANGLE RESTRAINTS WERE DERIVED FROM NOE RATIOS, SECONDARY STRUCTURE PROPENSITIES EVIDENT IN PRELIMINARY STRUCTURES, AND FROM ALPHA CARBON 13C CHEMICAL SHIFT TRENDS. RESIDUES 51-59 COMPRISE A POORLY-DEFINED LOOP IN THIS ENSEMBLE OF STRUCTURES. RESIDUES 92 TO 110 ARE ALSO NOT WELL-DEFINED IN THE ENSEMBLE.
