Jürgen Kahmannved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors. Ribosomes modified in this way are no longer able to carry out protein synthesis. Most RIPs exist as single polypeptides (Type 1 RIPs) which are largely non-toxic tLATE 发表于 2025-3-25 12:12:15

Jürgen KahmanneinsMany plants produce enzymes collectively known as ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of an adenine residue from a conserved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors.

A Phenomenological Study of Even-Even Nuclei in the Neutron-Proton I.B.A.eason, we did not try to get the best possible fit for each individual nucleus but rather attempted to reproduce the observed trends in excitation energies, binding energies, B(E2) etc. for a chain of isotopes or isotones.cauda-equina 发表于 2025-3-26 17:37:25
