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:0000256|ARBA:ARBA00003213, ECO:0000256|HAMAP-
CC       Rule:MF_00185, ECO:0000256|RuleBase:RU003784}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=adenosine(37) in tRNA + dimethylallyl diphosphate =
CC         diphosphate + N(6)-dimethylallyladenosine(37) in tRNA;
CC         Xref=Rhea:RHEA:26482, Rhea:RHEA-COMP:10162, Rhea:RHEA-COMP:10375,

CC         Rule:MF_00185, ECO:0000256|RuleBase:RU003783};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000256|HAMAP-Rule:MF_00185};
CC   -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_00185}.
CC   -!- SIMILARITY: Belongs to the IPP transferase family.
CC       {ECO:0000256|ARBA:ARBA00005842, ECO:0000256|HAMAP-Rule:MF_00185,
CC       ECO:0000256|RuleBase:RU003785}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC       feature annotation. {ECO:0000256|HAMAP-Rule:MF_00185}.
