RC STRAIN=MWYL1; RG US DOE Joint Genome Institute; RA Copeland A., Lucas S., Lapidus A., Barry K., Glavina del Rio T., RA Dalin E., Tice H., Pitluck S., Kiss H., Brettin T., Bruce D., RA Detter J.C., Han C., Schmutz J., Larimer F., Land M., Hauser L., RA Kyrpides N., Kim E., Johnston A.W.B., Todd J.D., Rogers R., Wexler M., RA Bond P.L., Li Y., Richardson P.; RT "Complete sequence of Marinomonas sp. MWYL1."; RL Submitted (JUN-2007) to the EMBL/GenBank/DDBJ databases. 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: Dimethylallyl diphosphate + adenine(37) in CC tRNA = diphosphate + N(6)-dimethylallyladenine(37) in tRNA. CC {ECO:0000255|HAMAP-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. CC {ECO:0000255|HAMAP-Rule:MF_00185}.
