Residues4
Aromatic residues form a significant part of the protein core, where they make tight interactions with multiple surrounding side chains. (lu.se)
Despite the dense packing of internal side chains, the aromatic rings of phenylalanine and tyrosine residues undergo 180° rotations, or flips, which are mediated by transient and large-scale "breathing" motions that generate sufficient void volume around the aromatic ring. (lu.se)
The field is beginning to gather such data for aromatic residues in a variety of environments, ranging from surface exposed to buried. (lu.se)
