Figure 19.7.5.1

180° ring flips of tyrosine and phenylalanine about the C^β—C¹ bond. On the left, the atom numbering is given and the $[\chi^{2}]$ rotation axis is identified with an arrow. The drawing on the right presents a view along the C^β—C¹ bond of a flipping ring in the interior of a protein, where the broken lines indicate a transient orientation of the ring plane during the flip. The circles represent atom groups near the ring, and arrows indicate movements of atom groups during the ring flip (Wüthrich, 1986).
