Accession
GO:0052381
Name
tRNA dimethylallyltransferase activity
Ontology
molecular_function
Synonyms
dimethylallyl-diphosphate:tRNA dimethylallyltransferase activity, tRNA isopentenyltransferase activity, tRNA prenyltransferase activity
Alternate IDs
GO:0004811
Definition
Catalysis of the reaction: dimethylallyl diphosphate + tRNA = diphosphate + tRNA containing 6-dimethylallyladenosine. Source: EC:2.5.1.75
Comment
Note that this activity was formerly know in GO and EC as 'tRNA isopentenyltransferase' (EC:2.5.1.8, GO:0004811), but it is now known that dimethylallyl diphosphate, rather than isopentenyl diphosphate, is the substrate.
