Ribosome-inactivating proteins (RIPs, EC 3.2.2.22) are plant enzymes that can inhibit the translation process by removing single adenine residues of the large rRNA. These enzymes are known to function in defense against pathogens, but their biological role is unknown, partly due to the absence of
Ribosome-inactivating proteins (RIPs) are cytotoxic enzymes that inhibit protein translation by depurinating ribosomal RNA. Although most plant RIPs are synthesized with leader sequences that sequester them away from the host ribosomes, several RIPs from cereals lack these signal peptides and
Apoptosis is an active form of programmed cell death (PCD) that plays critical roles in the development, differentiation and resistance to pathogens in multicellular organisms. Ribosome inactivating proteins (RIPs) are able to induce apoptotic cell death in mammalian cells. In this study, using
