(A–E) Examples of each base:ligand interaction type (base:base [B:B], base:amino acid [B:A], base:sugar [B:S], base:phosphate [B:Ph], and base:other [B:O]) observed in the crystal structures of ligand-bound aptamer domains of riboswitches. (F) Statistical distribution of different base:ligand interactions in the crystal structures.
