CATH Clusters

Superfamily P-loop containing nucleotide triphosphate hydrolases
Functional Family tRNA dimethylallyltransferase

Enzyme Information

2.5.1.75
tRNA dimethylallyltransferase.
based on mapping to UniProt P16384
Dimethylallyl diphosphate + adenine(37) in tRNA = diphosphate + N(6)- dimethylallyladenine(37) in tRNA.
-!- Formerly known as tRNA isopentenyltransferase (EC 2.5.1.8), but it is now known that dimethylallyl diphosphate, rather than isopentenyl diphosphate, is the substrate. -!- Formerly EC 1.8.6.1 and EC 2.5.1.8.
