Figure 7. Comparison of env22 (this study), Oryza sativa (4OJI) and env (4QJH) twister ribozymes.

Figure 7

a, In-line alignment of the U-A step in the 2.9 Å structure of the env22 twister ribozyme with the emphasis on the position of the modeled 2′-O of U relative to the adjacent P-O5′ bond. b, Off-line orthogonal alignment of the U-A step in the 2.3 Å structure of the Oryza sativa twister ribozyme (PDB: 4OJI). c, Off-line orthogonal alignment of the U-A step in the 4.1 Å structure of the env twister ribozyme (PDB: 4QJH).
