Molecular sterics guide tmRNA translocation on the ribosome

Translation of defective mRNA transcripts can lead to the formation of stalled “non-stop” ribosome complexes. To rescue these ribosomes, bacteria have evolved a mechanism called trans-translation that is mediated by transfer-messenger RNA (tmRNA) and small protein B (SmpB). During the translocation step of trans-transl...

Ribosomal protein bL27 protects translating ribosomes from tmRNA-SmpB

Trans-translation and bL27 data are linked and support a model in which the amino terminus of bL27 acts as a gatekeeper to prevent tmRNA from sterically interfering with tRNA (transfer RNA) on the ribosome.
