Secondary structure prediction of the tetR (A), σ70 (B), blyA (C), and agsA (D) RNA thermometers. The start codons for their respective downstream genes and the SD sequences are boxed and labeled. Stems in the structure are labeled with “P,” single-stranded loops are labeled with “L,” and a single-stranded region linking two stems is labeled “J1/2” to indicate the junction of stems one and two.
