Small RNAs, large networks: posttranscriptional regulons in gram-negative bacteria

K Papenfort, S Melamed - Annual review of microbiology, 2023 - annualreviews.org
Small regulatory RNA (sRNAs) are key mediators of posttranscriptional gene control in
bacteria. Assisted by RNA-binding proteins, a single sRNA often modulates the expression …
