IntEnz Enzyme Nomenclature
EC 3.1.13.1

Names

Accepted name:
exoribonuclease II
Other names:
5'-exoribonuclease
Escherichia coli exo-RNase II
BN ribonuclease
RNase II
exoribonuclease
ribonuclease II
ribonuclease Q
Systematic name:
-

Reaction

Comments:

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 ribonuclease P. Formerly EC 3.1.4.20.
