Enzyme Information
| 3.1.13.1 |
Exoribonuclease II.
based on mapping to UniProt Q9SF21
Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates.
-!- Preference for single-stranded RNA. -!- The enzyme processes 3'-terminal extra-nucleotides of monomeric tRNA precursors, following the action of EC 3.1.26.5. -!- Similar enzymes: RNase Q, RNase BN, RNase PIII, RNase Y. -!- Formerly EC 3.1.4.20.
