ID 3.1.13.5 DE Ribonuclease D. AN RNase D. CA Exonucleolytic cleavage that removes extra residues from the 3'-terminus CA of tRNA to produce 5'-mononucleotides. CF Cobalt or manganese or magnesium. CC -!- Alteration of the 3'-terminal base has no effect on the rate of CC hydrolysis whereas modification of the 3'-terminal sugar has a major CC effect. CC -!- tRNA terminating with a 3'-phosphate is completely inactive. CC -!- This enzyme can convert a tRNA precursor into a mature tRNA.
