Term Information

Accession
GO:0009022
Name
tRNA nucleotidyltransferase activity
Ontology
molecular_function
Synonyms
RNase PH activity, phosphate-dependent exonuclease activity, ribonuclease PH activity, tRNA:phosphate nucleotidyltransferase activity
Alternate IDs
None
Definition
Catalysis of the reaction: tRNA(n+1) + phosphate = tRNA(n) + a nucleoside diphosphate. Source: EC:2.7.7.56
Comment
Note that, although the enzyme to which this term refers is also known as 'ribonuclease PH', and degrades tRNA in the 3'-5' direction in vivo, the term does not have parentage in the 'nuclease activity' branch of the ontology because both GO and the Enzyme Commission define nuclease activity as a type of hydrolysis.
