EF-P-resolved ribosome stalling and collision trigger Rae1-mediated mRNA decay
Ribosome stalling compromises proteome integrity and cellular fitness, and requires efficient mechanisms to eliminate problematic mRNAs and rescue blocked ribosomes. We previously identified Rae1 as an endoribonuclease that cleaves mRNAs at the tail end of stalled ribosomes to promote mRNA degradation in Bacillus subtilis. Here, we show that Rae1 has a broader role in the quality control of mRNAs…
