2. Ribosomal Deceleration

   Linked via "$\beta$-turn"

   Deceleration Motifs (DMs)/)
   DMs are typically short, hydrophobic segments enriched in specific, non-polar amino acids, particularly Leucine ($\text{L}$) and Valine ($\text{V}$), separated by exactly five peptide bonds. The prevailing hypothesis suggests that the precise five-residue spacing allows the nascent chain to adopt a secondary structure (often a transient $\beta$-turn analogue) that transientl…
