Enzyme Information
| 3.1.26.3 | Ribonuclease III. based on mapping to UniProt Q9X0I6 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. |
