FIGURE 1. — Structures of selected tRNA elbow modifications and their locations within E. coli tRNA^Phe. (A) Structures of the 4-thiouridine, 7-methylguanosine, 5-methyluridine, and pseudouridine modifications. (B) The locations of these modifications within the tRNA elbow are highlighted as spheres within the crystal structure of unmodified tRNA^Phe (PDB 3L0U; Byrne et al. 2010). The enzyme responsible for each modification is indicated next to the respective modification site.
