Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 3.2Å Ligands: DST, MG, PPV, ZN Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function 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). Evolutionary Conservation Check, as determined by ConSurfDB.
