RiboDraw

RiboDraw: Semiautomated 2D representation of RNA 3D structures

RiboDraw generates two-dimensional (2D) drawings that represent three-dimensional (3D) RNA structures. It produces structured diagrams that annotate noncanonical base pairs, protein interactions, and structural motifs to reflect spatial organization within RNA molecules.

Key Features:

• 2D–3D Structural Mapping: Converts RNA 3D structural information into standardized 2D layouts that preserve spatial relationships.
• Functional Annotation: Highlights noncanonical base pairs, ribosomal proteins, and structural motifs within RNA secondary structure diagrams.
• Broad RNA Structure Support: Applied to diverse RNAs including Escherichia coli tRNA-Phe, the P4-P6 domain of the Tetrahymena ribozyme, a −1 ribosomal frameshift stimulation element from beet western yellows virus, the 5' untranslated region of SARS-CoV-2, and the 23S and 16S subunits of the Escherichia coli ribosome.

Scientific Applications:

• RNA Structural Analysis and Communication: Supports visualization, modeling, structural interpretation, and presentation of RNA architectures and ribonucleoprotein complexes.

Methodology:

RiboDraw uses a semiautomated workflow to translate RNA 3D structural coordinates into organized 2D secondary structure diagrams, manually refining layouts to preserve key spatial features such as noncanonical base pairing and protein–RNA interactions.
