THE RESOLUTION WAS THEN EXTENDED TO 1.7 ANGSTROMS. REFINEMENT AT THIS STAGE INVOLVED SIMULATED ANNEALING FOLLOWED BY B-FACTOR REFINEMENT, WITH THE EXTENSIVE USE OF SIMULATED ANNEALING OMIT MAPS. THE FINAL MODEL OBTAINED FROM X-PLOR WAS AGAIN REFINED WITH REFMAC. THE FINAL REFINEMENT STATISTICS FROM REFMAC ARE SHOWN HERE.
