AB The effects of 30 type 1 and of 2 (ricin and volkensin) type 2 ribosome-inactivating proteins (RIPs) on Escherichia coli and Agrobacterium tumefaciens cell-free translation systems were compared with the effects on a rabbit reticulocyte translation system. The depurinating activity of RIPs on E. coli ribosomes was also evaluated. Only six type 1 RIPs inhibited endogenous mRNA-directed translational activity of E. coli lysates, with submicromolar 50% inhibitory concentrations. Four RIPs had similar activities on poly(U)-directed phenylalanine polymerization by E. coli ribosomes, and three RIPs inhibited poly(U)-directed polyphenylalanine synthesis by A. tumefaciens ribosomes, with submicromolar 50% inhibitory concentrations.
