Figure 6. Likely Interdomain Interaction in V. cholerae Glycine Riboswitch.

Figure 6

(A) Projection of intermolecular interactions found in the VCII crystallographic dimer and NAIM sites (Mandal and Breaker, 2004) on the secondary structure of natural tandem riboswitch. Domain I is shown in cyan and domain II in black. Green circles indicate NAIM sites which cannot be explained by the structure of the individual VCII RNA. Orange shading shows areas that correspond to the regions involved in interdomain interactions in the crystallographic dimer of VCII RNA.

(B)-(C) Proposed interdomain interactions in the tandem natural riboswitch.
