FIGURE 2.
Singlet glycine riboswitches bind glycine as strongly as tandem riboswitches. (A) Diagrams of prototypical tandem (VC), type-1 singlet (Lmo), and type-2 singlet (Dha) riboswitches. (B) Glycine-binding curves for prototypical singlet and tandem riboswitches. VC WT is as reported in Ruff and Strobel (2014).
