RNA maturation is a key event regulating genes at post-transcriptional level. In bacteria, it is employed to adjust the amounts of proteins and functional RNAs, often in response to environmental constraints. During the process of RNA maturation, enzymes and factors that would otherwise promote RNA degradation convert a labile RNA into a stable and biologically functional molecule.
