UCSF Chimera is a program for the interactive visualization and analysis of molecular structures and related data, including density maps, trajectories, and sequence alignments. It is available free of charge for noncommercial use. Commercial users, please see Chimera commercial licensing.
We encourage Chimera users to try ChimeraX for much better performance with large structures, as well as other major advantages and completely new features. ChimeraX includes a significant subset of Chimera features (with more to come, see the missing features list) and is under active development. Users may choose to use both programs, and it is fine to have both installed.
Chimera is no longer under active development, and is only updated for critical maintenance. Chimera development was supported by a grant from the National Institutes of Health (P41-GM103311) that ended in 2018.
One use of Multidomain Assembler is to set up comparative modeling and concatenation of existing structures to generate a full-length model of a multidomain protein. However, even without model-building, the byproduct is also useful: a visual summary of the structures available for a query sequence, optionally filtered by criteria such as BLAST score and % identity, laid out horizontally in approximate N→C order relative to the query. Overlapping hits are stacked vertically, and segments without structural coverage are indicated with spheres. By default, the multiple sequence alignment of the hits to the query is also displayed.
The figure shows the results of command:
mda p08648 ~/Desktop/MDA limit 4 percent 50
with sequence mismatches in red and molecules other than the hit chains in blue. Text and pointers have been added with 2D Labels.
Multidomain Assembler is described in a paper.(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.
