The RNA helicase HrpA rescues collided ribosomes in E. coli

Annabelle Campbell, Hanna Esser, Alexander Maxwell Burroughs…·Allen R. Buskirk

The paper shows that HrpA, an RNA helicase in E. coli, rescues stalled ribosomes by splitting collided ribosomes into subunits using ATP hydrolysis.

Ribosome collisions in bacteria promote ribosome rescue by triggering mRNA cleavage by SmrB

Kazuki Saito, Hanna Kratzat, Annabelle Campbell…·Allen R. Buskirk

The paper identifies SmrB as a factor that cleaves mRNAs upstream of stalled ribosomes in bacteria, promoting ribosome rescue through ribosome collisions.
