Figure 3.
Fig. 3. (A) Stereo ribbon representation of the superposition of RRF (blue) and yeast tRNA^Phe (red) with Molmol (34). (B) Comparison of EF-G (36) and the ternary complex of EF-Tu + GDPNP + aatRNA (32). EF-G (left) is similar in shape to EF-Tu + GDPNP + aatRNA (right). Domain III-IV of EF-G (purple) imitates the shape of the tRNA (red) bound to EF-Tu (yellow). The remaining domains of EF-G (green) are structurally similar to EF-Tu. RRF (A) imitates the tRNA in a totally different manner. (C) Grasp (34) surface representation of the superposition of RRF (blue) and yeast tRNA^Phe (red). The shapes and sizes of the surfaces are nearly identical except for the acceptor end of tRNA (to the right), which has no corresponding part in RRF.
