UCSF ChimeraX
UCSF ChimeraX (or simply ChimeraX)
is the next-generation molecular visualization program from the
Resource for Biocomputing,
Visualization, and Informatics (RBVI),
following UCSF Chimera.
ChimeraX can be downloaded free of charge
for academic, government, nonprofit, and personal use.
Commercial users, please see
ChimeraX commercial licensing.
ChimeraX is developed with support from National Institutes of Health R01-GM129325.

Front/back (rotatable)
clipping
can be applied selectively to some models but not others.
This is most often used to slice a molecular surface
but not the corresponding atomic structure.
For example, the protein in PDB entry
1g74 has an oleic acid residue OLA in an interior pocket.
The script in pmc.cxc
shows the protein surface, activates front clipping for all models,
and then turns it off for just the atomic model, as shown in the figure.
The clipping plane can be translated and rotated interactively
with the mouse
.

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.
