Ribonuclease Y

Gene

rny

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Endoribonuclease that initiates mRNA decay. Initiates the decay of all SAM-dependent riboswitches, such as yitJ riboswitch. Involved in processing of the gapA operon mRNA, it cleaves between cggR and gapA (PubMed:19193632). Is also the decay-initiating endonuclease for rpsO mRNA.5 Publications

Disruption phenotypei

Essential; depletion mutants show a significant increase in global mRNA half-life (PubMed:19779461) a decrease in at least 1 specific mRNA processing event (PubMed:19193632); in a more severe depletion experiment alteration of about 26% of transcripts was seen (PubMed:22412379). Later shown not to be essential in 4 strains, with a doubled doubling time, cells are translucent, suggesting a possible cell surface defect. 168 trpC2 cells able to grow on minimal medium. Loss of competence for plasmid transformation, 1000-fold less sporulation. Increased sensitivity to a wide range of antibiotics. Thinner cells form long curved structures of 2-3 cell lengths, cell walls are altered with looser, considerably less dense peptidoglycan. Double pnp-rny mutants grow very slowly, while rnjA-rny mutants could not be isolated (PubMed:23504012).4 Publications

Interactioni

Subunit structurei

Homodimer (Probable). Component of a possible RNA degradosome complex composed of rny, rnjA, rnjB, pnp, pfkA and eno (PubMed:19193632) (although rnjA and rnjB's presence is unclear). Interacts with RNA helicase CshA which may also be a member of the RNA degradosome complex (PubMed:20572937).Curated4 Publications
