Figure 1. Localization of L30e in a 9.5-Å cryo-EM map of the 80S
ribosome. (a) Cryo-EM density of the wheat germ 80S ribosome
(accession code EMD-3361 in EMBL 3D-EM database). Yellow, 40S
subunit; blue, 60S subunit; green, P-site tRNA; magenta, L30e;
SB, stalk base; CP, central protuberance. Right density is
rotated by 150°. (b) L30e as part of the isolated 60S subunit
density. SRL, sarcin ricin loop. (c) 25S RNA secondary structure
diagram of domains II and III. Magenta, L30e-binding region of
helix 58 (R.R. Gutell, University of Texas at Austin,
