FunFam 9751: Ribonuclease 3

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Ribonuclease III. [EC: 3.1.26.3]
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.
