Contact graph and tertiary structure of 1R3E:A. Contact graph and tertiary structure of 1R3E:A. Binding residues are marked in yellow within the graph and the structure. RNA is displayed as cartoon in orange. Graph layout according to the Kamada-Kawai algorithm  and generated by the JUNG library. Node size proportional to averaged betweenness centrality (spatial patch with size 19). Note that edge lengths and node positions are not related to the spatial location of residues in the 3D structure.
