Fig. 1. Overview of the quasi-atomic model of the
50S·EF-G·GDPNP·RRF complex. (a) Stereo view
of the quasi-atomic structure of the
50S·EF-G·GDPNP·RRF complex superimposed
with the cryo-EM density map. (b) The same stereo view of the
quasi-atomic structure only. (c) Surface representation of the
cryo-EM density map. (d) Overview of the interactions between
EF-G and RRF. Ribosomal proteins, rRNAs, EF-G, and RRF are
painted in green, gray, red, and blue, respectively. The domains
of EF-G are labeled as I–IV. The two domains of RRF are
labeled as “tail” (domain I) and “head” (domain II).
Landmarks: L7L12, L7/12 stalk; L1, L1 stalk; CP, central
protuberance; arc, arc-like connection between EF-G and L7/L12
stalk base.
