Find PDB structures and Computed Structure Models (CSM) by combining queries from tools in this suite: Attribute Search, Sequence Similarity, Sequence Motif, 3D Similarity, and 3D Motif with 'AND' logic.
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.

Details
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.
