The structures are based on the total number constraints of 1220, including 1098 NOE-derived distance constraints, 104 dihedral angle constraints, 18 hydrogen bond constraints.
No peptide bond linking between residues 82 and 83 results from
disorder in the tail region of the protein and lack of restraints.
