Figure 6. Tertiary interactions of the AD-linker and variable arm.

Figure 6

(A) Water-mediated interaction of the AD-linker with the first bp of the variable arm in mouse tRNASec (molecule A – gold; molecule B – silver). Water molecules – cyan spheres. Hydrogen bonds are shown as dashed lines. (B) Close-up of the variable arm (molecule A). Nucleotides of the variable loop are labeled. (C) Superposition of the mouse tRNASec variable loop (carbon – gold) with a stable GAGA tetraloop from the 23S rRNA sarcin/ricin domain (carbon – cyan; PDB ID 483D).
