REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: REMARK 3 THE STRUCTURE ARE BASED ON: 1) TEN PAIRS OF INTER-SUBUNIT REMARK 3 DISTANCES FOR THE KCSA INNER REMARK 3 HELICAL BUNDLE IN THE CLOSED AND THE OPEN STATES AND 2) THE USE OF REMARK 3 THE CRYSTAL STRUCTURE REMARK 3 AS THE CHANNEL IN THE CLOSED STATE, AND AS THE REFERENCE REMARK 3 STRUCTURE. THE COMPUTER PROGRAM REMARK 3 REDCAT SEARCHES (RESTRAINT-DRIVEN CARTESIAN TRANSFORMATION) BASED REMARK 3 ON THE EXHAUSTIVE SAMPLING REMARK 3 OF RIGID-BODY MOVEMENT IN CARTESIAN SPACE FOR THE TM2 INNER BUNDLE REMARK 3 IN THE OPEN STATE WERE REMARK 3 ALLOWED TO CONVERGE TO A MINIMAL PENALTY VALUE. THE ENSEMBLE OF REMARK 3 THE 50 LOWEST PENALTY REMARK 3 CONFORMERS WAS SUBJECTED TO MOLECULAR MECHANIC ENERGY REMARK 3 MINIMIZATION. FINAL REFINEMENT WAS REMARK 3 PERFORMED ON THE AVERAGE OPEN HELICAL BUNDLE BY ENERGY REMARK 3 MINIMIZATION. REMARK 4 REMARK 4 1JQ1 COMPLIES WITH FORMAT V. 3.30, 13-JUL-11 REMARK 99 REMARK 99 THE STRUCTURE CONTAINS ONLY ALPHA-CARBONS BECAUSE REMARK 99 THE EXPERIMENTAL DATA USED TO CALCULATE THE STRUCTURES REMARK 99 ARE GOOD ENOUGH ONLY TO THE BACKBONE LEVEL.
