GO:0052381 tRNA dimethylallyltransferase activity

Term Information

ID GO:0052381
Name tRNA dimethylallyltransferase activity
Ontology Molecular Function
Definition Catalysis of the reaction: dimethylallyl diphosphate + tRNA = diphosphate + tRNA containing 6-dimethylallyladenosine.
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.
