Accepted name: exoribonuclease II
Reaction: Exonucleolytic cleavage in the 3′- to 5′-direction to yield nucleoside 5′-phosphates
Other name(s): ribonuclease II; ribonuclease Q; BN ribonuclease; Escherichia coli exo-RNase II; RNase II; exoribonuclease (misleading); 5′-exoribonuclease (misleading)
Comments: Preference for single-stranded RNA. The enzyme processes 3′-terminal extra-nucleotides of monomeric tRNA precursors, following the action of EC ribonuclease P.
