A New Paradigm of the African Stateosome. A curious feature of eIF-5 is that it also possesses a ribosome-dependent GTPase activity which is required in model assays using eIF-2A in place of eIF-2 to form initiation complexes (. et al. 1975; . et al. 1975).condemn 发表于 2025-3-27 05:59:45

The ability of a primordial GTPase to oscillate between GTP-and GDP-bound conformations furnished an opportunity for evolution to elaborate a diverse and vNATTY 发表于 2025-3-28 13:24:51

Two of these, elongation factor (EF-)Tu and EF-G, are GTPases. In its active form, EF-Tu-GTP forms a ternary complex with aminoacyl-tRNA and positions it in the A site of the rib
