Specificity of the ricin A chain-ribosome interaction was demonstrated by competition experiments using either ricin A chain or gelonin, another ribosome-inactivating protein having the identical mechanism of ribosome inactivation (26) in a broad spectrum of species including rat and rabbit (12, 26).
