aThe database contained 31 entries with Trp residues. Among them, only acyclic structures with short aromatic - aromatic (centroid - centroid distance between six membered rings of indole ≤ 6.5 Å) and / or aromatic - amide (centroid - centroid distance of five membered ring of indole and amide centroid ≤ 4.5 Å) distances are listed.
