Figure 1 Frequency of torsion angles observed in 46 ultra-high-resolution protein structures in 10° bins. See Table 2 for conversion between torsion angles defined by X-PLOR atom types and those labeled using the standard protein conformation angle nomenclature. Note that unlike the rest, the peptide -angle/5 of arginine runs from 0 to 360° to avoid splitting the peak across the two ends.
