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 Xref=Rhea:RHEA:26482, Rhea:RHEA-COMP:10162, Rhea:RHEA-COMP:10375,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:57623, ChEBI:CHEBI:74411,
CC ChEBI:CHEBI:74415; EC=2.5.1.75; Evidence={ECO:0000255|HAMAP-
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}.
