Figure 4. Crystal contacts of ΔGCCAtRNASec.
Stacking interactions of the terminal G1-C72 bp of the acceptor stem of molecule A with nucleotides G19 and U20 of the the D-loop of a neighboring molecule A. Left – overview. Right – close-up of the crystal packing interaction. In this and the following figures, atoms are color-coded in identical fashion; carbon – gold (or as the respective molecule); nitrogen – blue; oxygen – red; phosphorus – orange. Hydrogen bonds are indicated by dashed lines. The right view is rotated 45° about the horizontal axis as indicated.
