Abstract

The co-crystal structure of the T-box tRNA-binding region, stem I, bound to tRNA is solved, showing that this region not only binds the anticodon, but also cradles the entire tRNA, forming an extended interface; the two T-loop motifs of stem I mediate interactions similar to those of RNase P and the large ribosomal subunit, even though the three species do not share a common evolutionary ancestor.
