Protein Modeling and Structure Visualization

  • The tertiary structures of proteins can be viewed as three-dimensional figures that can be manipulated by user interaction. Additionally, quarternary structures such as those containing different protein sub-units or protein-DNA complexes can also be visualized using certain algorithms. RasMol and Chime are the most common of those tools.

  • RasMol is a popular interactive visualization and manipulation software available from and maintained at the University of Massachusetts. Each molecule to be viewed with RasMol needs an atomic coordinate file which is a file in the PDB (Protein Data Bank) format.

  • Chime is similar to Rasmol except that the molecules are shown using a Web Browser plug-in. Chime shows only the molecules written into the web page by its author. One can use the Chime software to develop web-based online tutorials on biomolecules with highly visual and interactive figures.
