Translational2
- Lacking classical Shine-Dalgarno (SD) sequences, messenger RNAs (mRNAs) of Bacteroidetes were recently shown to be enriched for adenine residues at position -3, -6, and -11 to -15 relative to the translational start codon, with adenine overrepresentation at these positions positively correlating with translation efficiency 8 .
