Fig. 3: Comparison of 16S rRNAs from S. solfataricus and P. abyssi.

a h16 and eS30 binding site. The cryo-EM structure of Ss-30S is shown on the left with the rRNAs helices of interest colored in red (S. solfataricus) or in light yellow (P. abyssi). eS6 is colored in cornflower blue. b Region of h10, h6, h44 and eS6 (cornflower blue) binding site. c Position of eS6 in the human ribosome (8QOI70). See also Supplementary fig. 8 for a description of eS6 in eukaryotes and archaea.
