Escherichia coli K-12 substr. MG1655 Reaction: 3.1.13.5

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.1.13.5

Enzymes and Genes:
RNase D Inferred from experiment : rnd
RNase T Inferred from experiment : rnt

In Pathway: tRNA processing

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Undetermined; a substrate lacks a chemical formula

Enzyme Commission Primary Name: ribonuclease D

Enzyme Commission Synonyms: RNase D

Enzyme Commission Summary:
This reaction is defined as the exonucleolytic cleavage that removes extra residues from the 3'-terminus of tRNA to produce 5'-mononucleotides.

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.
