Feature Highlight
The Presets menu includes a few different combinations of cartoon and nucleotide styles, shown here along with overall settings from the Publication preset plus lighting depthcue false. The style settings of cartoons and nucleotides can be controlled individually (and with many more possibilities than shown here) with cartoon style and nucleotides, respectively.

Example Image
The outer-membrane protein CymA admits bulky molecules into the periplasmic space of Klebsiella oxytoca. Here, CymA (PDB 4d5d chain A) is depicted in a style reminiscent of a diagnostic X-ray, with transparent molecular surface and β-strand “ribs” in white. The protein has ingested α-cyclodextrin (top) and β-cyclodextrin (bottom), bound at the entry site and near the exit, respectively. Cyclodextrin carbon atoms are shown in blue-gray and oxygen atoms in brick red. For image setup, see the command file xray.cxc.
