ENZYME entry: EC 3.1.13.5

Accepted Name
Ribonuclease D.
Alternative Name(s)
RNase D.
Reaction catalysed
Exonucleolytic cleavage that removes extra residues from the 3'-terminus of tRNA to produce 5'-mononucleotides
Cofactor(s)
Mg(2+) or cobalt cation or Mn(2+).
Comment(s)
  • Alteration of the 3'-terminal base has no effect on the rate of hydrolysis whereas modification of the 3'-terminal sugar has a major effect.
  • tRNA terminating with a 3'-phosphate is completely inactive.
  • This enzyme can convert a tRNA precursor into a mature tRNA.
