Regulation of RNase E during the UV stress response in the cyanobacterium sp. PCC 6803.

Endoribonucleases govern the maturation and degradation of RNA and are indispensable in the posttranscriptional regulation of gene expression. A key endoribonuclease in Gram-negative bacteria is RNase E. To ensure an appropriate supply of RNase E, some bacteria, such as , feedback-regulate RNase E expression via the 5'-untranslated region (5' UTR) in .
