Let's see how tmRNA rescues a stuck ribosome.


In the current issue, Weis et al (2010a) and Fu et al (2010) provide cryo-electron microscopy snapshots of different states of the bacterial ribosome-rescuing complex with tmRNA. This regulatory RNA molecule remarkably carries both tRNA- and mRNA-like elements that have to move through the ribosome machinery when it is stalled on an mRNA lacking a… (More)
