| + | [https://www.uniprot.org/uniprot/MOD5_YEAST MOD5_YEAST] Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in the anticodon loop on a specific subset of tRNAs both in the cytosol and the mitochondrion, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A). This modification optimizes the codon:anticodon fit in the ribosome and promotes translational fidelity. Competes with the farnesyl pyrophosphate synthase ERG20 for the common substrate dimethylallyl diphosphate (DMAPP).<ref>PMID:3031456</ref> <ref>PMID:10618371</ref> <ref>PMID:21873461</ref> | ||
