Figure 2
Stepwise improvements from trans to cis. (a) The peptide bond between Arg71 and Phe72 (ω = 132°) in PDB entry 2bmd (Huber & Scheidig, 2005BB24) needs a tc− flip. (b) The peptide has been flipped only `halfway' in PDB_REDO (ω = 81°). (c) The fully flipped and refined cis peptide (ω = 9°). The side chains have been omitted beyond Cβ for clarity. Maps are as in Fig. 1[link].
