Method Details Software
simulated annealing NOE intensities were converted into semi-quantitative distances restrains. The upper limits of the distances thus obtained were 2.8, 3.4 and 5.0A; (for strong, medium, and weak NOEs, respectively). Structure calculations were performed using the Xplor-NIH software, version 2.17.0 . Starting with the extended structure, 500 structures were generated using a simulated annealing protocol. This was followed by 20000 steps of simulated annealing at 1000 K and a subsequent decrease in tempera ure in 15000 steps in the first slow-cool annealing stage. 1
