For a nice 3D-printing protocol that uses Chimera, see 3D Printing of Biomolecular Models for Research and Pedagogy by Da Veiga Beltrame, Tyrwhitt-Drake, et al. today in JoVE!(Previous news...)
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, nonprofit, and personal use. Chimera is developed by the Resource for Biocomputing, Visualization, and Informatics (RBVI), funded by the National Institutes of Health (NIGMS P41-GM103311).
UCSF ChimeraX (or simply ChimeraX) is the next-generation molecular visualization program from the RBVI, following UCSF Chimera.
A structure can be colored to show attributes such as residue conservation. Opening a sequence alignment in Chimera shows it in Multalign Viewer and automatically associates sequences with structures as appropriate. Residues of alignment-associated structures are assigned conservation values; available measures include entropy, variability, and sum-of-pairs. The figure was created using the PFAM Carb_anhydrase seed alignment PF00194_seed.slx (see image) and includes 2D labels and a color key. See also: mapping sequence conservation(More features...)
Peroxiredoxins are enzymes that help cells cope with stressors such as high levels of reactive oxygen species. The image shows a decameric peroxiredoxin from human red blood cells (Protein Data Bank entry 1qmv), styled as a holiday wreath.
