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
Atomic structures and/or maps can be fit rigidly into other maps with the Map icon , the Fit in Map tool, or the fitmap command. A common use is to locally optimize the fit after initial placement by hand. The command includes options for symmetrical and sequential fitting, as well as global search to generate multiple starting points for local optimization.
Elongator is a highly conserved complex that associates with RNA polymerase II during transcriptional elongation. In the image, one of its six subunits, Elp2 (PDB 5m2n), has been fit into a map of the Elp123 subcomplex (EMDB 4151).
More features...Example Image
Atomic B-factor values are read from PDB and mmCIF input files and assigned as attributes that can be shown with coloring and used in atom specification. This example shows B-factor variation within a structure of the HIV-1 protease bound to an inhibitor (PDB 4hvp). For complete image setup, including positioning, color key, and label, see the command file bfactor.cxc.
Additional color key examples can be found in tutorials: Coloring by Electrostatic Potential, Coloring by Sequence Conservation
