A single DIMS transition of adenylate kinase (AdK) shows the opening of the salt bridge zipper. Salt bridges pairs are shown in the same colors as in Fig 7 in the manuscript. A line is shown between the two moieties while the distance is <10 Å. The LID domain is colored yellow, and the NMP domain is shown in light blue. The CORE domain (white) stays unchanged during the transition.
