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, Chan Zuckerberg Initiative grant EOSS4-0000000439, and the Office of Cyber Infrastructure and Computational Biology, National Institute of Allergy and Infectious Diseases.
Feature Highlight
Worms are specialized cartoons in which “fatness” reflects the values of an attribute such as bfactor or seq_conservation. In the example image, the average atomic B-factor per amino acid residue is shown with both coloring and worms. The structure is a trimer of E. coli porin (PDB 1pho). For image setup, see the command file worms.cxc.
Worms are available in ChimeraX v1.8 daily builds 3/12/24 and newer. Worms and coloring by attribute can be done with the Render by Attribute tool or commands cartoon byattribute (aka worm) and color byattribute.
More features...Example Image
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.
