RNAs can begin to fold immediately after emerging from RNA polymerase during transcription. Interactions between nascent RNAs and ligands during cotranscriptional folding can direct the formation of alternative RNA structures, a feature exploited by non-coding RNAs called riboswitches to make gene regulatory decisions. These sequencing datasets were generated using cotranscriptional SHAPE-Seq which measures structural information of nascent RNAs during transcription. The datasets describe the in vitro folding pathways of the B. cereus Fluoride riboswitch using a biotin-streptavidin RNA polymerase roadblocking strategy.核糖核酸（RNA）可在转录过程中从RNA聚合酶（RNA polymerase）脱离后即刻开始折叠。共转录折叠过程中，新生RNA（nascent RNA）与配体（ligand）的相互作用可引导替代性RNA结构的形成，这一特征被一类名为核糖开关（riboswitch）的非编码RNA（non-coding RNA）所利用，以做出基因调控决策。本测序数据集通过共转录SHAPE-Seq技术生成，该技术可在转录过程中检测新生RNA的结构信息。该数据集借助生物素-链霉亲和素（biotin-streptavidin）RNA聚合酶阻断策略，描述了蜡样芽孢杆菌（B. cereus）氟化物核糖开关的体外折叠通路。
