Method FOURIER DECONVOLUTION, CONFORMATIONAL GRID SEARCH A CARTESAIN REPRESENTATION MOLECULAR MECHANIC ENERGY MINIMIZATION
Details THE STRUCTURE ARE BASED ON: 1) TEN PAIRS OF INTER-SUBUNIT DISTANCES FOR THE KCSA INNER HELICAL BUNDLE IN THE CLOSED AND THE OPEN STATES AND 2) THE USE OF THE CRYSTAL STRUCTURE AS THE CHANNEL IN THE CLOSED STATE, AND AS THE REFERENCE STRUCTURE. THE COMPUTER PROGRAM REDCAT SEARCHES (RESTRAINT-DRIVEN CARTESIAN TRANSFORMATION) BASED ON THE EXHAUSTIVE SAMPLING OF RIGID-BODY MOVEMENT IN CARTESIAN SPACE FOR THE TM2 INNER BUNDLE IN THE OPEN STATE WERE ALLOWED TO CONVERGE TO A MINIMAL PENALTY VALUE. THE ENSEMBLE OF THE 50 LOWEST PENALTY CONFORMERS WAS SUBJECTED TO MOLECULAR MECHANIC ENERGY MINIMIZATION. FINAL REFINEMENT WAS PERFORMED ON THE AVERAGE OPEN HELICAL BUNDLE BY ENERGY MINIMIZATION.
