Molecule Structure Prediction & Visualization Tools

  • Cn3D
Cn3D is a visualization tool for biomolecular structures, sequences, and sequence alignments. Cn3D apart from other software correlate structure and sequence information: for example, a scientist can quickly find the residues in a crystal structure that correspond to known disease mutations, or conserved active site residues from a family of sequence homologs. Cn3D displays structure-structure alignments along with their structure-based sequence alignments, to emphasize what regions of a group of related proteins are most conserved in structure and sequence.


  • RasMol
It is a powerful research tool to display the structure of DNA, proteins, and smaller molecules. Protein Explorer, a derivative of RasMol, is an easier to use program.


  • Swiss Model
Swiss-PdbViewer is an application that provides a user friendly interface allowing to analyze several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and compare their active sites or any other relevant parts. Amino acid mutations, H-bonds, angles and distances between atoms are easy to obtain thanks to the intuitive graphic and menu interface.
