The cytidine at the first anticodon position of archaeal tRNA(Ile2), which decodes the isoleucine AUA codon, is modified to 2-agmatinylcytidine (agm(2)C) to guarantee the fidelity of protein biosynthesis. This post-transcriptional modification is catalyzed by tRNA(Ile)-agm(2)C synthetase (TiaS) using ATP and agmatine as substrates. Archaeoglobus fulgidus TiaS was overexpressed in Escherichia coli cells and purified. tRNA(Ile2) was prepared by in vitro transcription with T7 RNA polymerase. TiaS was cocrystallized with both tRNA(Ile2) and ATP by the vapour-diffusion method. The crystals of the TiaS-tRNA(Ile2)-ATP complex diffracted to 2.9 Å resolution using synchrotron radiation at the Photon Factory. The crystals belonged to the primitive hexagonal space group P3(2)21, with unit-cell parameters a = b = 131.1, c = 86.6 Å. The asymmetric unit is expected to contain one TiaS-tRNA(Ile2)-ATP complex, with a Matthews coefficient of 2.8 Å(3) Da(-1) and a solvent content of 61%. << Less

A modified base at the first (wobble) position of some tRNA anticodons is critical for deciphering the genetic code. In eukaryotes and eubacteria, AUA codons are decoded by tRNAsIle with modified bases pseudouridine (and/or inosine) and lysidine, respectively. The mechanism by which archaeal species translate AUA codons is unclear. We describe a polyamine-conjugated modified base, 2-agmatinylcytidine (agm(2)C or agmatidine), at the wobble position of archaeal tRNA(Ile) that decodes AUA codons specifically. We demonstrate that archaeal cells use agmatine to synthesize agm(2)C of tRNA(Ile). We also identified a new enzyme, tRNA(Ile)-agm(2)C synthetase (TiaS), that catalyzes agm(2)C formation in the presence of agmatine and ATP. Although agm(2)C is chemically similar to lysidine, TiaS constitutes a distinct class of enzyme from tRNA(Ile)-lysidine synthetase (TilS), suggesting that the decoding systems evolved convergently across domains. << Less
