(A) The secondary structure of SAM-III riboswitch. The blue shaded area shows the Shine-Dalgarno (SD) sequence, GGGGG. (B) The tertiary structure of SAM-III riboswitch. (C) The structure of the metabolite S-adenosylmethionine, which in the coarse-grained simulations is represented using two interaction centers corresponding to the regions shown in red dotted lines. One of the centers corresponds to the adenosol (base and the ribose on the right) and the other represents the methionine moiety on the left.
