The cytotoxin sarcin disrupts elongation factor binding and protein synthesis by specifically cleaving one phosphodiester bond in ribosomes. To elucidate the molecular basis of toxin action, we determined three cocrystal structures of the sarcin homolog restrictocin bound to different analogs that mimic the target sarcin/ricin loop (SRL) structure of the rat 28S rRNA ...
