β-lactoglobulin is a dimeric protein that exists in two forms. BLG A and BLG B, which differ by two mutations, one of which is a non-charged residue being replaced by an Aspartic Acid, which at relevant pH values is negatively charged. The result is a protein that exists in two isoforms, which differ by two negative charges (one per monomer).
The differences between these two forms significantly augment the electrostatic potential, making BLG A & BLG B an ideal system for studying the interaction of a protein with a polyelectrolyte.
