RNase H from E. coli is an endoribonuclease that specifically hydrolyzes the phosphodiester bonds of RNA in RNA:DNA duplexes to generate products with 3'-hydroxyl and 5'-phosphate ends.1,2,3 RNase H degrades only the RNA component of the DNA-RNA hybrid (RNA that is hydrogen bonded to a complementary DNA strand). Other enzymes in E. coli which degrade RNA in the DNA-RNA hybrid are DNA polymerase I and exonuclease III, but these degrade either the RNA or DNA of the hybrids. Ribonuclease H will not cleave single-stranded or double-stranded DNA or RNA.1,2
