BACKBONE AND SIDECHAIN REMARK 3 ASSIGNMENTS WERE DETERMINED MANUALLY FROM TRIPLE-RESONANCE REMARK 3 NMR DATA. NOE DISTANCE RESTRAINTS WERE DERIVED MANUALLY REMARK 3 FROM NOESY DATA. THE STRUCTURE IS BASED ON 1235 RESTRAINTS: REMARK 3 938 NOE DISTANCE RESTRAINTS, 112 H-BOND RESTRAINTS (56 H-BONDS), REMARK 3 AND 185 DIHEDRAL RESTRAINTS. PHI DIHEDRAL RESTRAINTS WERE DERIVED REMARK 3 FROM THE HNHA EXPERIMENT AND TALOS. PSI DIHEDRAL RESTRAINTS WERE REMARK 3 DERIVED FROM NOE RATIOS, SECONDARY STRUCTURE PROPENSITIES EVIDENT REMARK 3 IN PRELIMINARY STRUCTURES, ALPHA CARBON CHEMICAL SHIFTS, AND TALOS. REMARK 3 RESIDUES 1-2 AND 182-194 ARE UNSTRUCTURED TERMINI IN THIS ENSEMBLE.
