IntEnz Enzyme Nomenclature
EC 3.1.13.5

Names

Accepted name:
ribonuclease D
Other name:
RNase D
Systematic name:
-

Reaction

Cofactor

Comments:

Requires divalent cations for activity (Mg2+, Mn2+ or Co2+). 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 [3]. This enzyme can convert a tRNA precursor into a mature tRNA [2].
