REMARK 3 SIMONSON, G.L. WARREN (CNS) REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: REMARK 3 THERE WERE A TOTAL OF 1016 DISTANCE RESTRAINTS (INCLUDING 48 REMARK 3 HYDROGEN BOND DISTANCE RESTRAINTS) AND 167 TORSION RESTRAINTS USED REMARK 3 TO DETERMINE THIS STRUCTURE. THE MOLECULAR MODELING OF THE PHI21 REMARK 3 N PEPTIDE-BOXB RNA COMPLEX WAS DONE IN THREE STEPS. FIRST, A REMARK 3 COMPLETE INTRAMOLECULAR RESTRAINT SET WAS GENERATED FOR EACH REMARK 3 MOLECULE, AND THEN PEPTIDE AND RNA STRUCTURES WERE GENERATED REMARK 3 SEPARATELY USING AB INITIO SIMULATED ANNEALING (SA) STARTING FROM REMARK 3 A RANDOM EXTENDED STRUCTURE IN CNSSOLVE. FOR BOTH THE PEPTIDE AND REMARK 3 THE RNA, CONSTRAINED (TORSION) DYNAMICS WAS USED AT 50000K. A REMARK 3 TOTAL OF 100 STRUCTURES EACH OF THE PEPTIDE AND RNA WERE GENERATED. REMARK 3 IN THE SECOND STEP, EACH OF THE 20 LOWEST ENERGY PEPTIDE AND REMARK 3 20 LOWEST ENERGY RNA STRUCTURES WERE COMBINED IN SINGLE PDB FILES, REMARK 3 IN ALL 400 POSSIBLE COMBINATIONS. THE RNA WAS HELD AT THE ORIGIN REMARK 3 AND THE PEPTIDE WAS RANDOMLY ROTATED AND MOVED 100 ANGSTROMS AWAY REMARK 3 IN A RANDOM DIRECTION FROM THE ORIGIN. THESE 400 POSSIBLE " REMARK 3 COMPLEXES" WERE DOCKED USING CNSSOLVE. THE OBJECTIVE OF THE REMARK 3 DOCKING WAS TO BRING THE PEPTIDE AND RNA TOGETHER WITHOUT REMARK 3 DRAMATICALLY PERTURBING THEIR FOLDED STRUCTURES FROM THE FIRST REMARK 3 ROUND OF SA, SO THE TEMPERATURES FOR THE DOCKING WERE SET MUCH REMARK 3 LOWER THAN IN THE INITIAL CALCULATIONS (1000 VS. 50000K). REMARK 3 FINALLY, THE 100 LOWEST ENERGY DOCKED STRUCTURES WERE REMARK 3 MINIMIZED BY TWO ROUNDS OF LOW TEMPERATURE ANNEALING USING SANDER, REMARK 3 A MODULE OF AMBER. AS WITH THE DOCKING, THE TEMPERATURE WAS KEPT REMARK 3 LOW (1000K). THE 14 LOWEST ENERGY STRUCTURES WERE USED FOR REMARK 3 GENERATING AN AVERAGE STRUCTURE, WHICH WAS ENERGY MINIMIZED USING REMARK 3 A CONJUGATE GRADIENT.
