Figure 3

Interactions between a mutant riboswitch and c-di-GMP and c-di-AMP. a. Interactions made by the G20A/C92U mutant riboswitch and Gα. Coloring is the same as in Figure 2. b. Interactions made by the G20A/C92U mutant riboswitch and Gβ. Coloring is the same as in Figure 2. c. Interactions made by the G20A/C92U mutant riboswitch and Aα. c-di-AMP is colored by atom with nitrogen colored blue, oxygen colored red, phosphorus colored orange, and carbon colored white. Riboswitch nucleotides are colored by atom with nitrogen colored blue, oxygen colored red, phosphorus colored orange, and carbon colored yellow. Hydrogen bonds are denoted by black dashed lines. d. Interactions made by the G20A/C92U mutant riboswitch and Aβ. Coloring is the same as in part c.
