Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. rpoS mRNA encodes for the rpoS stress factor, sigma E, where DsrA in conjunction with the Sm like RNA binding protein, Hfq promote the translation of this rpoS mRNA. The 5'' UTR of the rpoS mRNA forms a self inhibitory stem loop that shields the shine-dalgarno sequence and therefore inhibits translation. The secondary structure of the 5''UTR was predicted by acetylation of ribose 2''hydroxyls with NMIA and by using a secondary structure prediction program, RNAstructure. DsrA stimulates rpoS translation by binding in the 5''UTR and causes the stem loop to open, exposing the ribosome binding site. Site-directed mutagenesis and deletion analysis located an AAYAA motif identified upstream of the stem loop structure which is required for Hfq binding. Comparative genomics has showned that this regulatory secondary structure is conserved across several gram negative bacteria species. Site-directed mutagenesis is a molecular biology technique in which a mutation is created at a defined site in a DNA molecule, usually a circular molecule known as a plasmid. In general, site-directed mutagenesis requires that the wild type gene sequence be known.
