Analysis of programmed frameshifting during translation of in .

Ribosomes of Bacteroidia fail to recognize Shine-Dalgarno (SD) sequences due to sequestration of the 3' tail of the 16S rRNA on the 30S platform. Yet in these organisms, the gene typically contains the programmed +1 frameshift site with its characteristic SD sequence. Here, we investigate autoregulation in , a member of the Bacteroidia.
