FIGURE 2.

Crystal structure of the RNA aptamer-TetR-complex (PDB 6SY4, Grau et al. 2020). (A) Cartoon representation of dimeric TetR (in blue and gray) in complex with the TetR aptamer. Amino- and carboxyl termini and 5′ and 3′ ends are labeled, helix-turn-helix motifs formed by the helices α2 and α3 of each monomer are colored in dark blue. Stick representation of the nucleotides A7 and G8 are displayed in red. (B) Close up view of the TetR aptamer interface. (C) Stick representation of G8, G33, Tyr42′, and Lys46′.
