ROSE1 and ROSEAT2
ROSE1 and ROSEAT2 are specific examples of ROSE elements. ROSE1 is found in Bradyrhizobium japonicum whereas ROSEAT2 is a closely related element from Agrobacterium tumefaciens. The two RNA elements have similar secondary structures with ROSE1 having an extra hairpin. All ROSE elements contain a characteristic 'bulged G' opposite the Shine-Dalgarno sequence binding site, without this nucleotide the RNA thermometer loses its temperature-sensitivity.
