Figure 6
The translational noncrystallographic symmetry (TNCS). The TNCS is mediated by a single hydrogen bond between Arg138 NH and the carbonyl of Gly186 and has a hydrogen-bond distance of 2.7 Å. (a) Close-up view, (b) zoomed-out view. This figure was prepared with CCP4mg (McNicholas et al., 2011). The standard uncertainty in this hydrogen-bond distance is 0.5 Å and was calculated using Online_DPI (Kumar et al., 2015). |
