REMARK 3 PROGRAM : CHARMM 31A0 REMARK 3 AUTHORS : BROOKS ET AL. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: AN EXHAUSTIVE DOCKING STUDY OF REMARK 3 CHOLESTEROL BINDING IN THE CAVITY OF MLN64-START WAS CARRIED REMARK 3 OUT TO IDENTIFY AND CLASSIFY THE POSSIBLE BINDING MODES THAT REMARK 3 CHOLESTEROL MAY ADOPT IN THE MLN64 CAVITY (PDBID: 1EM2). MD REMARK 3 SIMULATIONS WERE SUBSEQUENTLY USED TO MORE THOROUGHLY SAMPLE REMARK 3 CONFORMATIONS OF THE PROTEIN-LIGAND COMPLEX (10 INDEPENDENT REMARK 3 RUNS OF 1.5 NS EACH). ALL MD SIMULATIONS WERE PERFORMED USING REMARK 3 VERSION C31A0 OF THE CHARMM BIOMOLECULAR SIMULATION SOFTWARE REMARK 3 ALONGSIDE THE CHARMM22/CMAP ALL-ATOM PROTEIN FORCE FIELD. AN REMARK 3 IMPLICIT MODEL OF THE SOLVENT WAS USED IN ALL SIMULATIONS, AS REMARK 3 IMPLEMENTED IN THE GBSW MODULE OF CHARMM.
