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 Institute of General Medical Sciences (R01-GM129325; previously P41-GM103311) and the National Institute of Allergy and Infectious Diseases.

Feature Highlight

Cartoon/Nucleotide Presets

The Presets menu includes a few different combinations of cartoon and nucleotide styles, shown here along with overall settings from the Publication preset plus lighting depthcue false. The style settings of cartoons and nucleotides can be controlled individually (and with many more possibilities than shown here) with cartoon style and nucleotides, respectively.

Photosynthetic Reaction Center

The photosynthetic reaction center from a purple sulfur bacterium is shown as a cartoon with “tube” helices and membrane boundaries from the OPM database (Orientations of Proteins in Membranes, entry 1eys). Blue and red balls represent the cytoplasmic and periplasmic sides of the bacterial inner membrane, respectively. The title and other text labels were added with the 2dlabels command and repositioned interactively with the move label mouse mode . ChimeraX session file: prc.cxs
