So, what is the purpose of the UTR? It turns out that the leader sequence is important because it contains a ribosome-binding site. In bacteria, this site is known as the Shine-Dalgarno box ...

During the elongation cycle of protein biosynthesis on the ribosome ... Along with the binding positions of EF-G, in the GDP and GTP states, the positions of A-, P- and E-site tRNAs have been ...

These rRNAs play a role in peptide bond formation and translocation. The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome ...

They were able to observe the smooth bending motion of inter-subunit bridge proteins and the spring-like transitions of tRNA between ribosome-binding sites, which had not been previously seen in ...
