Analysis of internal protein interactions
Tcontacts (Tcons: Tertiary Contacts) allows for a fast and accurate analysis internal protein interactions. Given a PDB file to upload your own file (specifying PDB functionality under construction) and the chain of interest, TCons will provide a graphical representation of the residues in tertiary contact. The contact map will not only indicate the internal contacts present, 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 the internal packing between proteins.
A valid PDB file.
