Witryna12 kwi 2024 · However, due to the high concentration of endogenous ribosomes, the chances of two modified subunit assembling into an orthogonal ribosome are low (Orelle et al., 2015). To overcome this, the ribosome subunits were tethered together with an RNA linker. In Ribo-T, the 23S rRNA is connected to the 16S rRNA by two poly A … Witryna27 maj 2016 · Many antibiotics target the ribosome and interfere with its translation cycle. Since translation is the source of all cellular proteins including ribosomal proteins, protein synthesis and ribosome assembly are interdependent. As a consequence, the activity of translation inhibitors might indirectly cause defective ribosome assembly. …
