Structure of the MsrE-ribosome complex. (A) Overall structure of the MsrE-ribosome complex. The 50S and 30S subunits are shown in orange and cyan, respectively, and the tRNA and mRNA are in purple and blue, respectively. (B) Interactions of the MsrE ABC1 domain with the 50S subunit L1-stalk (23S rRNA helices H68 and H76) and of the ABC2 domain with the 30S subunit (16S rRNA helices h41 and h42 and r-protein S7), r-protein L5, and tRNA. (C) MsrE domain linker helical region interactions with 50S subunit 23S rRNA and P-site tRNA.
