Webb10 apr. 2024 · Complete answer: In bacterial and archaeal messenger RNA, a ribosomal binding site is present which is located around 8 bases upstream of the start codon AUG is called the Shine–Dalgarno (SD) sequence which is common in bacteria, but rarer in archaea, also present in some chloroplast and mitochondrial transcripts. Webbto ribosome binding might be expected to have a similar effect. For example, the binding of ribosomes to even a good RBS can be inhibited by competitive binding of a regulatory protein. Such inhibition is typically accompa-nied by a reduction in mRNA longevity. Thus, the Sm-like protein Hfq and ribosomal protein L1 (the rplA gene product) each ...
