THE HP62 MONOMERS WERE SUBSEQUENTLY DUPLICATED AND DOCKED ONTO A B-DNA TEMPLATE STRUCTURE OF THE LAC OPERATOR, WHICH WAS ALLOWED TO BEND IN ORDER TO ACCOMODATE THE TWO HP62 MONOMERS. THE PROPERLY DOCKED STRUCTURES WERE PLACED IN A TIP3P WATERBOX WHICH WAS NEUTRALIZED BY ADDITION OF SODIUM-IONS. THE STRUCTURES WERE THEN FURTHER REFINED BY A RESTRAINED MD SIMULATION OF 24 PS IN THE CHARMM22 FORCEFIELD FOR PROTEINS AND NUCLEIC ACIDS. NCS SYMMETRY RESTRAINTS WERE USED DURING THE DOCKING AND REFINEMENT PROCEDURES. FOR FURTHER REFINEMENT DETAILS SEE THE PAPER DESCRIBING THE STRUCTURES | ||||||||||||
