摘要：
TiaS catalyzes the transfer of agmatine onto the first position cytidine of the tRNAIle2 anticodon in archaea, ensuring proper translation of the matching codon. Now the crystal structures of the TiaS–tRNAIle2 complex with ATP, or with AMPCPP and agmatine, reveal a novel kinase domain and show how TiaS selects the correct tRNA while segregating the target cytidine until agmatine is bound.
