Ribonuclease III.
based on mapping to UniProt O67082
Endonucleolytic cleavage to 5'-phosphomonoester.
-!- An endoribonuclease that cleaves double-stranded RNA molecules. -!- The cleavage can be either a single-stranded nick or double-stranded break in the RNA, depending in part upon the degree of base-pairing in the region of the cleavage site. -!- Specificity is conferred by negative determinants, i.e., the presence of certain Watson-Crick base-pairs at specific positions that strongly inhibit cleavage. -!- RNase III is involved in both rRNA processing and mRNA processing and decay.
