Several lighting modes are available, including ambient occlusion.
The image shows hemoglobin (PDB
4hhb)
with the four chains shown as surfaces of different colors and
heme residues as spheres. The command
lighting soft
or the Graphics
icon
can be used to turn on ambient shadowing from 64 directions. The command
lighting gentle
gives a similar result, except tuned to emphasize larger indentations.

Influenza neuraminidase is an enzyme that promotes the spread of influenza
virus among host cells.
It is the target of oseltamivir and related antiviral drugs.
The image shows tetramers of neuraminidase (PDB
3k3a) styled as flowers. Three tetramers are in different
shades of pink, with a central metal ion in white and nearby residues in yellow,
and a fourth tetramer is colored green to resemble leaves.
Each monomer or “petal” is a six-bladed β-propeller.
For image setup other than orientation,
see the command file flowers.cxc.
