Intermolecular interactions along the trimer 3-fold axis of TSP3 catalytic domain. (a) Stereoscopic representation of intramolecular charge-charge interaction. For clarity, the residue labeling and interactions are shown for only one molecule, but the same interactions repeat in triplicates. (b) The stacking of threonine residues along the β-helix rungs proceeding His367. Again, residues labels are shown for only one molecule.
