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). {ECO:0000255|HAMAP-Rule:MF_00185}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=adenosine(37) in tRNA + dimethylallyl diphosphate =
CC         diphosphate + N(6)-dimethylallyladenosine(37) in tRNA;

CC         Rule:MF_00185};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00185};
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00185}.
CC   -!- SIMILARITY: Belongs to the IPP transferase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00185}.
