Position of the Ribosomal Proteins S15, L33, and L36 in the 70S Ribosome.
Shown are the 16S rRNA (pink ribbon) and the S15 protein (dark gray and yellow)
of the small ribosomal subunit (30S) as well as the 23S rRNA (gray ribbon), the
L33 (light blue and yellow), and the L36 (brown) proteins of the large
ribosomal subunit (50S).
(A) Localization of S15, L33, and L36 in relation to the 16S and
23S rRNAs.
(B) Close-up view revealing the interaction of S15 with the 23S
rRNA via an RNA loop that protrudes into the 30S subunit.
