A single DIMS transition of AdK shows the opening of the salt bridge zipper. Salt bridges pairs are shown in the same colors as in Fig 7. A line is shown between the two moieties while the distance is <10A. The LID domain is colored yellow, and the NMP domain is shown in light blue. The CORE domain (white) stays unchanged during the transition. (Prepared with VMD and rendered with Tachyon.) Copyright (c) 2009 Oliver Beckstein and Elizabeth J. Denning.
