Abstrakt: Lectins from Aegopodium podagraria(APA), Bryonia dioica(BDA), Galanthus nivalis(GNA), Irishybrid (IRA) and Sambucus nigra(SNAl), and a new lectin-related protein from Sambucus nigra(SNLRP) were studied to ascertain whether they had the properties of ribosome-inactivating proteins (RIP). IRA and SNLRP inhibited protein synthesis by a cell-free system and, at much higher concentrations, by cells and had polynucleotide:adenosine glycosidase activity, thus behaving like non-toxic type 2 (two chain) RIP. APA and SNAl had much less activity, and BDA and GNA did not inhibit protein synthesis.
