Regulatory ncRNAs (non-coding RNAs) adjust bacterial physiology in response to environmental cues. ncRNAs can base-pair to mRNAs and change their translation efficiency and/or their stability, or they can bind to proteins and modulate their activity. ncRNAs have been discovered in several species throughout the bacterial kingdom. This review illustrates the diversity of physiological processes and molecular mechanisms where ncRNAs are key regulators.
