  "summary": "Ribotoxins disable ribosomes by cleaving ribosomal RNA, but how repair enzymes recognize and restore these damaged machines remains unclear. Here, we report three cryo-electron microscopy structures of the RNA ligase RtcB2 bound to damaged Escherichia coli 30S subunits. An extended interface stabilizes the ribosomal head and decoding-center scaffold while positioning the cleaved 3'-phosphate end…",
