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, Chan Zuckerberg Initiative grant EOSS4-0000000439, and the Office of Cyber Infrastructure and Computational Biology, National Institute of Allergy and Infectious Diseases.
Feature Highlight
 |
 |
A cryoelectron microscopy map of the 26S proteasome
(EMD-4321) is shown at the author-recommended contour level
in two different lighting modes: “simple” on the left
and “soft” on the right.
Soft lighting includes ambient lighting and shadowing (occlusion)
and can be turned on with the command
lighting soft
or by clicking the
Graphics
icon
.
For setup of the righthand image, see the command file ambient.cxc.
More features...Example Image
The GDP- and GTP-bound conformations of the transducin α-subunit (1tag and 1tnd, respectively) differ primarily in three regions, termed switch 1, switch 2, and switch 3. The structures have been superimposed with matchmaker and shown as cartoons, with “empty” outlines where the structures are almost the same (for simplicity, only one conformation's outlines are shown). The GTP analog GTPγS is displayed as spheres color-coded by heteroatom. For 2D labels and image setup other than structure orientation, see the command file switch.cxc.
