CC   -!- FUNCTION: Catalyzes the transfer of a dimethylallyl group onto the
CC       adenine at position 37 in tRNAs that read codons beginning with
CC       uridine, leading to the formation of N6-(dimethylallyl)adenosine
CC       (i(6)A) (By similarity).
CC   -!- CATALYTIC ACTIVITY: Isopentenyl diphosphate + tRNA = diphosphate +
CC       tRNA containing 6-isopentenyladenosine.
CC   -!- COFACTOR: Magnesium (By similarity).
CC   -!- SUBUNIT: Monomer (By similarity).
CC   -!- SIMILARITY: Belongs to the IPP transferase family.
