Ribonuclease 3

Gene

rnc

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Digests double-stranded RNA. Involved in the processing of ribosomal RNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Also processes pre-scRNA (the precursor of the signal recognition particle RNA). Probably also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Probably processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.4 Publications

Catalytic activityi

Endonucleolytic cleavage to 5'-phosphomonoester.

Disruption phenotypei

Essential. Depletion leads to the accumulation of 30S precursor rRNA (PubMed:11123676), and alteration of levels of about 11% of total transcripts (PubMed:22412379).3 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
