FIGURE 1.
Large subunit 50S, including P-tRNA (gray), polyAla chain (turquoise) and ribosomal proteins protruding to the ribosomal tunnel, namely uL4 (pink), uL22 (brown), uL23 (red) are shown. Nucleotides A2451 (PTC), A2062, U2585–U2586 (ribosomal tunnel), and residues Gly91 (tip of uL22 loop), Glu18 (trigger factor binding site on uL23), Gln72 (tip of uL23 loop), which are investigated in this study are also indicated. In all figures, PyMol (DeLano Scientific LLC., 2002) is used for the molecular visualization.
