Organism
Nostoc sp. (strain PCC 7120 / SAG 25.82 / UTEX 2576)
Function
Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism (By similarity).
Similarity
Belongs to the ribonuclease III family.
