"Ribosomes are very large macromolecular machines that very rapidly and precisely decode mRNA into protein. For a long time, they've been viewed as kind of 'dumb code-reading machines' that don't ...

The catalytic center of the ribosome, known as the peptidyl transferase center (PTC), is composed entirely of rRNA. The PTC is highly conserved across all domains of life, highlighting the fundamental ...

For these short RAPs, it has been determined that conserved amino acid residues are necessary to induce arrest by either directly binding the effector molecule or by acting at the peptidyl-transferase ...
