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 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

Elp2 fit into map of Elongator subcomplex

Fitting to Density Maps

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).

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
