based on the three-dimensional structure of the tRNA molecule. Other classes of RNA species include microRNAs, small interfering RNAs, and sRNAs—all of which are not translated into proteins but ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

The crystal structure of pseudouridine synthase I from Escherichia coli, which, for example, modifies positions 38, 39 and/or 40 in tRNA, reveals a dimeric protein that contains two positively ...
