Protein: Ribonuclease E (RNase E) (EC 3.1.26.12) (A0R152)
Organism: Mycolicibacterium smegmatis (strain ATCC 700084 / mc(2)155) (Mycobacterium smegmatis)
Function: Endoribonuclease that plays a central role in RNA processing and decay. Plays a major role in pre-16S rRNA maturation, probably generating the mature 5'-end, and a minor role in pre-5S and pre-23S rRNA maturation. Probably also processes tRNA (By similarity).
Subcellular location: Cytoplasm {ECO:0000269|PubMed:35521527}. Note=Has dynamic expression patterns, often present as foci near the mid-cell or new cell pole in addition to a weaker overall cytoplasmic distribution. Colocalizes with HupB (PubMed:35521527). {ECO:0000269|PubMed:35521527}.
