Method	Details	Software
simulated annealing	50 INITIAL STRUCTURES WERE CALCULATED USING A SIMULATED ANNEALING PROTOCOL WITHIN THE PROGRAM X-PLOR. THESE STRUCTURES WERE THEN ENERGY MINIMIZED USING 1000 CYCLES OF CONJUGATE GRADIENT MINIMIZATION WITH A REFINED FORCEFIELD BASED ON THE PROGRAM CHARMM [BROOKS ET AL. (1983) J. COMPUT. CHEM., 4, 187-217].	X-PLOR
