Nascent polypeptides undergo various cotranslational maturation steps, including N-terminal enzymatic processing, chaperone-assisted folding and membrane targeting. Kinetic analyses now demonstrate that N-terminal processing enzymes have fast ribosome binding kinetics, and premature chaperone recruitment or folding negatively affects processing efficiency, thereby separating nascent chain processing from later events.
