An unusual mechanism for EF-Tu activation during tmRNA-mediated ribosome rescue
In bacteria, ribosomes stalled on truncated mRNAs are rescued by transfer-messenger RNA (tmRNA) and its protein partner SmpB. Acting like tRNA, the aminoacyl-tmRNA/SmpB complex is delivered to the ribosomal A site by EF-Tu and accepts the transfer of the nascent polypeptide. Although SmpB binding wi...
