Ribosomal Quality Control

Caption

Contrary to the conventional view, the ribosome does not release individual proteins directly into the cystol after synthesis (left). Instead, it holds the protein back until chaperones deliver the matching counterparts (right). This way the ribosome assures that only the one intended structure is formed, thereby adopting the role of a quality inspector in addition to production.
