ARTEM: THE tool for RNA 3D motif identification, with backbone permutations!

ARTEM identifies RNA tertiary motifs based purely on their isostericity. We applied it to search for kink-turn-like motifs and discovered two new kink-turn topologies, multiple no-kink variants of the motif, and showed that a ribosomal junction in bacteria forms either a kink or a no-kink variant depending on the species (see the Figure). We also identified kink-turns in the catalytic core of group II introns, whose structures have not previously been characterized as containing kink-turns.

ARTEM opens a fundamentally new way to study RNA 3D folds and motifs and analyze their correlations and variations.
