simulated annealing, torsion angle dynamics | Because the backbone resonances of residues 158-191 are largely missing, only residues 8-157 of Mg2+-CIB1 are presented in this entry. Simulated annealing was done in two steps, 1st step, 200k-20k; 2nd step, 20K-2K, refer to J Biomol NMR. 2000 Nov;18(3):217-27. (Chou and Bax) | X-PLOR NIH |
