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).
Protein backbone angles can be shown in a Ramachandran Plot along with probability contours (green lines) from a reference set of well-determined structures. Each amino acid residue is shown as a dot in a graph of φ vs. ψ, more commonly known as a Ramachandran plot or Ramachandran map. Residues are shown as blue dots, or when selected, as red dots. In the example, all helix residues have been selected. Conversely, clicking a dot in the plot will select the corresponding residue in the structure. When the plot has mouse focus, the cursor position (x = φ, y = ψ) is reported under the plot.(More features...)
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.
