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.
