In cells, RNAs likely adopt numerous intermediate conformations prior to formation of functional RNA-protein complexes. We used single-nucleotide resolution selective 2'-hydroxyl acylation analyzed by primer extension (SHAPE) to probe the structure of Escherichia coli 16S rRNA in healthy growing bacteria. SHAPE-directed modeling indicated that the predominant steady-state RNA conformational ensemble in dividing cells had a base-paired structure different from that expected on the basis of… CONTINUE READING
