Abstract
tRNA identity elements assure the correct aminoacylation of tRNAs by the aminoacyl-tRNA synthetases with the cognate amino acid. The tRNA Gly/glycyl-tRNA sythetase system is member of the so-called ‘class II system’ in which the tRNA determinants consist of rather simple elements. These are mostly located in the tRNA acceptor stem and in the glycine case additionally the discriminator base at position 73 is required. Within the glycine-tRNA synthetases, the archaebacterial/human and the eubacterial sytems differ with respect to their protein structures and the required tRNA identity elements, suggesting a unique evolutionary divergence. In this study, we present a comparison between the crystal structures of the eubacterial Escherichia coli and the human tRNA Gly acceptor stem microhelices and their surrounding hydration patterns.
