Comparison of elongation-factor interactions with the 16S rRNA shoulder and L9 crystal-packing interactions with the same region. (a) Fusidic acid-locked structure of EF-G in complex with the 70S ribosome (Gao et al., 2009). In the left panel, EF-G is shown as a brown ribbon and the 30S ribosome is shown in grey. In the right panel, the EF-G surface is shown in transparent brown, the 30S ribosome in grey and the L9 crystal contacts in the same colours as in Fig. 3(b). (b) Kirromycin-locked structure of EF-Tu and tRNA with the 70S ribosome (Schmeing et al., 2009). In the left panel, EF-Tu is shown as a brown ribbon, tRNA is shown in magenta and the 30S ribosome in grey. In the right panel, the EF-Tu surface is shown in transparent brown, the 30S ribosome in grey and the L9 crystal contacts in the same colours as in Fig. 3(b). |
