Figure 3.

Change in relative translation speed (Y-axis) on the transition between secondary structures (X-axis). In moving from coil into helix (A) or coil into strand (B) a clear decrease in translation speed is observed. The transition from helix into coil (C) or strand into coil (D) is also characterized by a decrease in translation speed. In this instance, around three residues downstream of (N-terminal to) the transition site. This is followed by an increase in translation speed as the coil region is produced. Data shown for Ecoli using a speed window of three codons.
