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 licensing.

ChimeraX development is supported in part by grants from the National Institutes of Health (currently R01-GM129325, previously P41-GM103311).

Feature Highlight

Paired-10 palette
PuOr-5 palette

Color Palettes

A “palette” or ordered series of colors is used to color items sequentially (rainbow) or by values such as density. The ten chains in PDB 5o3l (paired tau filament) have been colored with the commands shown as 2D labels in the images. The first two examples at left use predefined palettes (credit to www.ColorBrewer.org, color specifications and designs by Cynthia A. Brewer, Pennsylvania State University), whereas the third shows specifying colors individually.

transducin switch regions

G-Protein Switch Regions

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.
