Different representations of nucleotides can be shown with the nucleotides command or Toolbar icons. Options include filled rings, slabs for bases (box, muffler, or ellipsoid shape), bumps on slabs to show base orientation, simple tubes instead of ribose atoms, and continuous or broken ladder rungs. Nucleotide representations can be the same color as the ribbon or a different color, and multiple nucleotide styles can be used within a single structure.

Example Image
The photosynthetic reaction center from a
purple sulfur bacterium is shown as a cartoon with “tube” helices
and membrane boundaries from the OPM database (Orientations of Proteins in Membranes,
entry 1eys).
Blue and red balls represent the cytoplasmic and periplasmic sides
of the bacterial inner membrane, respectively.
The title and other text labels were added with the
2dlabels
command and repositioned interactively with the move label
mouse mode
