Exoribonuclease H (EC 3.1.13.2) is an enzyme. [1] This enzyme catalyses the following chemical reaction

3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid

This is a secondary reaction to the RNA 5'-end directed cleavage 13-19 nucleotides from the RNA end performed by EC 3.1.26.13 (retroviral ribonuclease H).
