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

Feature Highlight

membrane protein with lipophilicity coloring

Coloring by Molecular Lipophilicity Potential

Molecular lipophilicity potential (MLP) can be calculated for a protein and displayed with surface coloring using the command mlp. The image shows the photosynthetic reaction center from a purple sulfur bacterium, with MLP coloring on the molecular surface and membrane boundaries from OPM (Orientations of Proteins in Membranes entry 1eys). Blue and red balls represent the cytoplasmic and periplasmic sides of the bacterial inner membrane, respectively. Parts of the L, M, and H chains span the membrane, whereas the cytochrome subunit sits on the periplasmic side, at the top. The surface coloring ranges from dark goldenrod for the most hydrophobic potentials, through white, to dark cyan for the most hydrophilic. Ligands including lipid, detergent, heme, and various other cofactors are shown as purple surfaces. For image setup, see the command file mlp.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.
