REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.1 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: DETAILS OF THE STRUCTURE REMARK 3 DETERMINATION AND ALL STRUCTURAL STATISTICS ARE GIVEN IN THE REMARK 3 PAPER CITED ON *JRNL* RECORDS ABOVE. THE STRUCTURE IS BASED ON REMARK 3 941 INTRAMOLECULAR CONSTRAINTS WITHIN THE BOUND TOXIN REMARK 3 (INCLUDING 291 LONG-RANGE INTERACTIONS), 98 INTRAPEPTIDE REMARK 3 INTERACTIONS (INCLUDING 7 LONG-RANGE INTERACTIONS), AND 62 REMARK 3 INTERMOLECULAR CONSTRAINTS BETWEEN THE BUNGAROTOXIN AND THE REMARK 3 13-RESIDUE PEPTIDE USED IN THIS STUDY (LISTED HERE AS RESIDUES REMARK 3 75 B - 87 B).
