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
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.
