Home-Page Site-Map

This table contains links which will lead to display of a representative example of a conformer in an interactive KiNG display window. Below is essentially Table 1 - Characteristics of the 46 consensus clusters of RNA backbone suite conformation - from the RNA Ontology Consortium paper, "RNA backbone: Consensus all-angle conformers and modular string nomenclature" doi/10.1261/rna.657708. We may periodically update the statistics and representatives on this table.

To view and interact with the structural model for a chosen example, click the "KiNG" button in the column labeled "example". Drag with the left mouse button to rotate in 3D, and click on a point to identify it. Buttons in the righthand panel can turn on all-atom contacts (both H-bonds & vdW) for the suite, and either full structure for the local neighborhood or pseudo-backbone for a larger context. Suitable views are on the "Views" pulldown menu.
