REMARK 3 (X-PLOR NIH) REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE REFINEMENT PROTOCOL CONSISTED OF REMARK 3 SLOW COOLING FROM 1000 K TO 100 K SPANNING 45 PS. FINAL REMARK 3 STRUCTURES WERE ENERGY-MINIMIZED USING 250 STEPS OF POWELL REMARK 3 ENERGY MINIMIZATION. THE 20 STRUCTURES WITH LOWEST ENERGY WERE REMARK 3 SUBJECTED TO FURTHER ANALYSIS AND SPIN-LABELED CYS RESIDUES REMARK 3 ASSOCIATED WITH PRE RESTRAINTS WERE CHANGED BACK TO THEIR WILD REMARK 3 TYPE RESIDUES. POWELL ENERGY MINIMIZATION WAS THEN PERFORMED. REMARK 4 REMARK 4 2K21 COMPLIES WITH FORMAT V. 3.30, 13-JUL-11 REMARK 100 REMARK 100 THIS ENTRY HAS BEEN PROCESSED BY RCSB ON 21-MAR-08.
