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.
Atomic structures and/or maps can be fit rigidly into other maps with the fitmap command or the Map icon . A common use is to locally optimize the fit after initial placement by hand. Options include 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...
Influenza neuraminidase is an enzyme that promotes the spread of influenza virus among host cells. It is the target of oseltamivir and related antiviral drugs. The image shows tetramers of neuraminidase (PDB 3k3a) styled as flowers. Three tetramers are in different shades of pink, with a central metal ion in white and nearby residues in yellow, and a fourth tetramer is colored green to resemble leaves. Each monomer or “petal” is a six-bladed β-propeller. For image setup other than orientation, see the command file flowers.cxc. The Chimera Image Gallery includes a similar image.
