Secondary structures provide a convenient way of exploring ribosomal RNAs and are familiar to many scientists. To facilitate navigating the RNA 3D Motif Atlas, we labeled publicly available 2D diagrams of rRNAs with links to RNA 3D motif instances from the Motif Atlas.

We used Representative sets of RNA 3D structures to choose representative structures for each molecule type and linked secondary structure diagrams with their motif instances. All motifs and motif instances are assigned unique and stable identifiers, so even as new structures become available, it will be possible to track the current motif group for each motif instance using the versioning system built into the RNA 3D Motif Atlas.
