Webβ-Amanitin is a cyclic peptide toxin in the poisonous Amanita phalloides mushroom. Besides, β-Amanitin inhibits eukaryotic RNA polymerase II and III. It inhibits DNA transcription and protein synthesis. Moreover, β-Amanitin can be used as a cytotoxic component of antibody-drug conjugates (ADCs). β-Amanitin (0.01-100 µg/mL; 36 hours) … WebAbstract. The mechanism of action of diphtheria toxin in an Escherichia coli cell-free protein-synthesizing system was examined. When the washed ribosomes were incubated with toxin before addition of messenger ribonucleic acid (RNA), peptide syntheses of 14 C-phenylalanine directed by polyuridylic acid or phage R17 RNA were strongly inhibited by a …
WebDec 24, 2024 · A protein synthesis inhibitor is a substance that stops or slows the growth or proliferation of cells by disrupting the processes that lead directly to the generation of new proteins. It usually refers to substances, such as antimicrobial drugs, that act at the … Similar to other A-B toxins, diphtheria toxin is adept at transporting exogenous proteins across mammalian cell membranes, which are usually impermeable to large proteins. This unique ability can be repurposed to deliver therapeutic proteins, instead of the catalytic domain of the toxin. This toxin has also been used in neuroscientific and cancer research to ablate specific populations of cells which express the diphtheria toxin receptor (heparin-binding EGF-like growt…
