What is it about?
Native clostridial GDH is a hexamer but detailed sequence and structure allow us to destabilise particular subunit interfaces to see if one can make stable trimers, dimers, monomers. In this study we constrcucted stable dimers.

Why is it important?
We wanted to know first whether smaller oligomers are active and secondly, if so, whether they retain allosteric properties. These dimers ,though stable and well-folded are not active. In fact subsequent studies would seem to indicate that intersubunits interaction in formation of the complete hexamer is required to permit activity.
