In 1984, MicF, the first base-pairing RNA encoded by the E. coli genome to be discovered, was shown to regulate the expression of the major outer membrane porin, OmpF (Mizuno et al. 1984).Twenty years later, with the renewed interest in sRNA regulators, five additional sRNAs that modulate expression of …
Webencourages the expression of OmpC, which has a smaller channel than OmpF, thus limiting the influx of large and charged molecules such as bile salts and antibiotics, while low osmotic pressure encourages the activity of OmpF [1].
