Mechanisms for ribotoxin-induced ribosomal RNA cleavage

Fungal ribotoxins are a group of extracellular ribonucleases (RNases) secreted by fungi. Their most notable characteristic is their extraordinary specificity. They inactivate ribosomes by cutting a single phosphodiester bond of the rRNA that is found in a universally conserved sequence. This cleavage leads to cell death by apoptosis. However, since they are extracellular proteins, they must first enter the cells that constitute their target to exert their cytotoxic action. This entry constitute… WebbリボヌクレアーゼT1; 関 ribonuclease T1 WordNet. the 20th letter of the Roman alphabet (同)t; PrepTutorEJDIC. tritiumの化学記号; Wikipedia preview
