Previous news...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 and the Office of Cyber Infrastructure and Computational Biology, National Institute of Allergy and Infectious Diseases.
Feature Highlight
Chain-chain interfaces can be identified by buried surface areas
and displayed as a network diagram with the
interfaces
command or the
Molecule Display
icon
.
In the diagram, nodes (circles) represent chains,
larger for greater surface areas,
and edges (lines) between nodes represent chain-chain interfaces
(default ≥ 300 Å2 buried area).
Dotted lines represent interfaces smaller than half the size of the
largest in the structure. Diagram context menus enable a variety of actions,
such as “exploding” the structure by moving chains apart,
hiding all but the chains in contact with a given chain,
and showing a more detailed plot of the residues forming a given interface.
The structure is an HIV envelope glycoprotein trimer bound by three copies of a broadly neutralizing antibody (PDB 5v8m), with chain information shown in the Log. Glycosylations (not displayed) were included in the surface area calculations. For setup, see the command file trimer-network.cxc.
More features...Example Image
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.
