Analysis of protein binding interfaces

  • Jerry Tsai


Short Description

Home Page

QContacts[1] allows for a fast and accurate analysis of protein binding interfaces. Given a PDB file to upload your own file (specifying PDB functionality under construction) and the interacting chains of interest, QContacts will provide a graphical representation of the residues in contact. The contact map will not only indicate the contacts present between the two proteins, but will also indicate whether the contact is a packing interaction, hydrogen bond, ion pair or salt bridge (hydrogen-bonded ion pair). Contact maps allow for easy visualization and comparison of protein-protein interactions.




A single valid PDB containing the coords for both structures.
