ArfB can displace mRNA to rescue stalled ribosomes
Alternative rescue factor B (ArfB) is an enzyme that releases peptides from stalled ribosomes to allow ribosome recycling. Here the authors carry-out cryo-EM analyses of 70S ribosomes complexed with ArfB on either a short or longer mRNA to reveal distinct modes of ArfB function.
