Upcoming Events

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

Feature Highlight

3w1k assembly 1

Assembly from mmCIF Symmetry Information

Multimeric assemblies defined in a structure's mmCIF file can be listed in the Log and built using 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.

Example Image

The Human Ribosome

The architecture of the human ribosome has been determined at near-atomic resolution by electron microscopy (Anger et al., Nature 497:80 (2013)). The structure, comprising 82 proteins and five RNA molecules, is shown with shadows cast from all directions to accentuate depth. In the background are schematic representations of contacts between the component molecules.
