Histograms showing distribution of torsion angles and distances between labels across the 31-model cluster. (a) Φ angle and (b) Ψ angle values for the backbone torsion angles between the two carbonyl labels [1-13C]P33 and [1-13C]Y34. Nitrogen-carbon distances between the (c) [15N]Y38 label and the [1-13C]P33 label and between the (d) [15N]Y38 label and the [1-13C]P34 label. Fluorine-carbon distances between the (e) [4′-19F]P23 label and the [1-13C]P33 label and between the (f) [4′-19F]P23 label and the [1-13C]P34 label.
