Upcoming Events

September 24, 2019

At 12 pm EDT, Tristan Croll will give a live webinar on using ISOLDE, a ChimeraX plugin for interactively building high-quality atomic models into density maps of low-to-medium resolution. Later, the presentation will be posted on SBGridTV.

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

Stylized Nucleotides

Different representations of nucleotides can be shown with the nucleotides command or Toolbar icons. Options include filled rings, slabs for bases (box, muffler, or ellipsoid shape), bumps on slabs to show base orientation, simple tubes instead of ribose atoms, and continuous or broken ladder rungs. Nucleotide representations can be the same color as the ribbon or a different color, and multiple nucleotide styles can be used within a single structure.

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
