Exoribonuclease II (EC 3.1.13.1, ribonuclease II, ribonuclease Q, BN ribonuclease, Escherichia coli exo-RNase II, RNase II, exoribonuclease (misleading), 5'-exoribonuclease) is an enzyme.[1][2][3][4] This enzyme catalyses the following chemical reaction

Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates

This enzyme has preference for single-stranded RNA.
