title: Two-step pathway to aminoacylated tRNA.
abstract: The 3.0 Angstrom crystal structure of a tRNA-dependent amidotransferase from the hyperthermophilic archaeon Pyrococcus abyssi provides the first detailed insight into how cells lacking canonical tRNA synthetases nonetheless carry out protein synthesis with high fidelity.
