RNAJunction

RNA is versatile in both its structure and function. Within this database you will to able to find more than 12,000 extracted three-dimensional junction and kissing loop structures as well as detailed annotations for each. If you are interested in RNA as a building block for nano-scale design or if you are analyzing the properties of specific RNA motifs you should find utility in this site.

The junctions in this database were extracted using a junction scanning algorithm from a number of structures from the Protein Data Bank. Coming from parent structures, both NMR and crystal, these junctions may be under contextual constraints. It is possible that these constraints play a critical role in the junction's conformation and stability.
