X-Pro C=O flip at atomic resolution. The central peptide Val129-Pro130 is shown in (a) the 1.2 Å resolution PDB entry 4gqr (Williams et al., 2012) and (b) the corresponding PDB_REDO structure. Note that in the PDB_REDO conformation not only the local backbone, but also the Val (Cγ1 pointing towards the reader) and Pro side chains fit the density much better. Colours and maps are as in Fig. 1. |
