Results of matchmaps.ncs for NCS-related molecules of PDZ. A variant of MatchMaps (implemented in the command line as matchmaps.ncs) can be used to compute internal difference maps across an NCS operation. (a) An overview of the three PDZ domains related by non-crystallographic symmetry. Chain A is shown in red, chain B in green and chain C in blue. Residues Cys606 and Cys645, which can form a disulfide bond, are shown in orange. The coloring matches Fig. 2(c) from the report by Mishra et al. (2007BB20). (b) The same as panel (a), plus a copy of chain C, shown in light blue, aligned and superimposed onto chain B. (c) A close-up on the disulfide bond formation. Chain C (light-blue sticks) contains a disulfide bond between Cys606 and Cys645, whereas chain B (green sticks) does not. The positive (blue) and negative (green) difference density corresponding to each chain is clearly visualized by MatchMaps.
