Caption: 3D interactive visualization of selected RNA structural features enabled by the DSSR-Jmol integration (http://jmol.x3dna.org). Clockwise from upper left: Structure of the xpt-pbuX guanine riboswitch in complex with hypoxanthine (PDB id: 4fe5) in ‘base blocks’ representation. The three-way junction loop encompassing the metabolite (in space-filling representation) is color-coded by base identity: A, red; C, yellow; G, green; U, cyan. The loop-loop interaction (a kissing-loop motif) at the top is highlighted in red (upper left corner). Structure of the Thermus thermophilus 30S ribosomal subunit in complex with antibiotics (PDB id: 1fjg) in step diagram. The 16S ribosomal RNA is color-coded in spectrum with the 5′-end in blue and the 3′-end in red (upper middle). Structure of the classic L-shaped yeast phenylalanine tRNA (PDB id: 1ehz) in step diagram, with the three hairpin loops highlighted in red and the [2,1,5,0] four-way junction loop in blue (upper right corner). Structure of the Pistol self-cleaving ribozyme (PDB id: 5ktj), showcasing (in red) the horizontal helix in space-filling representation. The helix is composed of six short stems stabilized via coaxial stacking interactions (bottom).

load =5ktj/dssr

The 'raw' images were automatically generated from the corresponding script files via command line using the Jmol application with options -ions. The ImageMagick convert program was used to remove empty boundaries. Using 4fe5 as an example, the procedure is as follows:

Code: [Select]
jmol -ions 4fe5.scr   # generate 4fe5-raw.png
convert -trim +repage -border 10 -bordercolor white 4fe5-raw.png 4fe5.png

The four images were then combined using InkScape, and exported to one big composite PNG file (DSSR-Jmol-for-NAR17-web-cover.png, 18MB).


Finally, the tarball file, reproduce-dssr-jmol.tar.gz, contains all the scripts and data files for reproducing the cover image.
