NMR Refinement
Method SUBSTRUCTURE EMBEDDING, SIMULATED ANNEALING, MATRIX RELAXATION
Details REFINEMENT PROCEDURE 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 8 OF 20 STRUCTURES. THE DIMER POSSESSES A TWO-FOLD AXIS OF SYMMETRY. THE TRANSFORMATION PRESENTED ON *MTRIX* RECORDS BELOW WILL YIELD APPROXIMATE COORDINATES FOR CHAIN B OF MODEL 1 WHEN APPLIED TO CHAIN A OF MODEL 1. THE COORDINATES OF THE ATOMS OF CHAIN A TRANSFORMED IN THIS MANNER HAVE AN RMSD OF 0.0015 ANGSTROMS FROM THE COORDINATES OF CHAIN B GIVEN IN THIS ENTRY.
