Ribonuclease T (RNase T, exonuclease T, exo T) is a ribonuclease enzyme involved in the maturation of transfer RNA and ribosomal RNA in bacteria, as well as in DNA repair pathways. It is a member of the DnaQ family of exonucleases and non-processively acts on the 3' end of single-stranded nucleic acids. RNase T is capable of cleaving both DNA and RNA, with extreme sequence specificity discriminating against cytosine at the 3' end of the substrate.
