Method SIMULATED ANNEALING, MATRIX RELAXATION
Details STEP (1) SUBSTRUCTURE EMBEDDING ON 20 STRUCTURES STEP (2) TEMPLATE FITTING AND REGULARIZATION BY SIMULATED ANNEALING (20 STRUCTURES) STEP (3) SIMULATED ANNEALING AND ENERGY MINIMIZATION (20 STRUCTURES) STEP (4) RELAXATION MATRIX REFINEMENT ON THE BEST 6 OF 20 STRUCTURES THIS PROCEDURE WAS CARRIED OUT SEPARATELY WITH DISTANCE RESTRAINTS ENFORCING HYDROGEN BONDING BETWEEN T4 AND T13 INVOLVING O2 ATOMS IN ONE CASE (MODELS 1-6) AND O4 ATOMS IN THE OTHER (MODELS 7-12). ALL MODELS WERE SUPERIMPOSED ON MODEL 1, USING ALL NON-HYDROGEN ATOMS OF G1, G2, G5, G6, G10, G11, G14, G15; I.E., ALL G RESIDUES PARTICIPATING IN TETRAD FORMATION.
