Therefore, we used a similar or identical design of figures and wording of figure legend explanations to those in our previous reports [4, 5]. The underlying data on SAM-I riboswitches (Supplementary Figure S4) are derived from a previously established alignment [1]. The data on SAM-IV riboswitches is novel.
