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 the National Institutes of Health (NIGMS P41-GM103311).

Feature Highlight

3w1k assembly 1

Assemblies from mmCIF Symmetry Information

Multimeric assemblies defined in a structure's mmCIF file are automatically listed when the file is opened and can be reconstituted with the sym command. The complex of selenocysteine synthase and tRNASec (PDB 3w1k) is shown as molecular surfaces of different colors for different chains. The asymmetric unit is on the left and the assembly specified in the mmCIF file is on the right, with arrow and text annotations from 2dlabels. See the command file sym.cxc.

Cyclodextrin Pore

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.
