EC Ribonuclease D. [1 PDB entries]    

Reaction: Exonucleolytic cleavage that removes extra residues from the 3'-terminus of tRNA to produce 5'-mononucleotides.
Other name(s): RNase D.
Cofactor(s): Mg(2+) or cobalt cation or Mn(2+).
Comments: 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.
