We are delighted to announce the publication of a new book, Computational and Visualization Techniques for Structural Bioinformatics Using Chimera, written by Forbes J. Burkowski (University of Waterloo).(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, 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).
Structures and their pocket measurements can be fetched directly from the Computed Atlas of Surface Topography of proteins (CASTp) database or read from local files previously returned by the CASTp server. In Chimera, the pockets are shown in a pocket list. Choosing rows in the list performs actions such as zooming in on pockets and selecting the surrounding atoms.
The figure shows the four largest pockets by volume identified by CASTp for PDB entry 1ovh (a cavity mutant of T4 lysozyme), shown in yellow, orange, pink, and magenta in order of decreasing volume. The largest is lysozyme's active site, with two openings. The second largest is the engineered cavity. Mutated positions are shown in red. Green balls are Cl– ions.(More features...)
The image shows interactions of the delta-1 loop with the rest of hepatitis C virus RNA-dependent RNA polymerase (Protein Data Bank entry 1quv). Loop residues in contact with the rest of the structure (van der Waals overlap ≥ 0.01 Å) are displayed as sticks; interacting surface atoms are shown as red patches. (More samples...)
