Example of an experimentally determined 3D structure of RNA with modified residues. Sequences of experimentally determined RNAs containing modifications are now imported to MODOMICS from the RSCB PDB database, with links to the original structural data. Here, the sequence of tRNA(Phe) from S. cerevisiae (RCSB ID 1ehz chain A) is shown, with modified ribonucleotide residues colored in red. In the corresponding sequence modified residues are indicated with the MODOMICS ribonucleoside codes and are also colored in red.
