Upcoming Events
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.
Feature Highlight
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
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.
The Chimera Image Gallery includes a similar image.
