Upcoming Events

UCSF Chimera is a highly extensible program for interactive visualization and analysis of molecular structures and related data, including density maps, supramolecular assemblies, sequence alignments, docking results, trajectories, and conformational ensembles. High-quality images and animations can be generated. Chimera includes complete documentation and several tutorials, and can be downloaded free of charge for academic, government, non-profit, and personal use. Chimera is developed by the Resource for Biocomputing, Visualization, and Informatics, funded by the National Institutes of Health (NIGMS P41-GM103311).

Feature Highlight

Consurf coloring and alignment

Showing ConSurf Results

The ConSurf Server provides results as Chimera Web data; after browser configuration, a single click displays the color-coded query structure and multiple sequence alignment with phylogenetic tree and custom headers in a locally installed copy of Chimera (details).

Special thanks to Elana Erez and the Ben-Tal and Pupko groups at Tel Aviv University, and to Fabian Glaser at the Technion.

Thermosome

Thermosomes are hollow balls inside which proteins are folded. They are found in the cytosol of eukaryotes and in archaea. Eukaryotic thermosomes have 8 different protein subunits, while archaeal ones are composed of one, two or three different proteins. The one shown from Thermoplasma acidophilum has two distinct proteins colored blue and yellow, each present in 8 copies. The two proteins have 60% sequence identity and are very similar in structure. One monomer is shown as a ribbon. Actin and tubulin are folded by eukaryotic thermosomes.

Protein Data Bank model 1a6d.
