High-resolution crystal structures of large ribosomalsubunits from Deinococcus radioduranscomplexed withtRNA-mimics indicate that precise substrate positioning,mandatory for efficient protein biosynthesis with no furtherconformational rearrangements, is governed by remoteinteractions of the tRNA helical features. Based on thepeptidyl transferase center (PTC) architecture, on theplacement of tRNA mimics, and on the existence of a two-fold related region consisting of about 180 nucleotides ofthe 23S RNA, we proposed a unified mechanism integra-ting peptide bond formation, A-to-P site translocation, andthe entrance of the nascent protein into its exit tunnel. ...
