I recently had a case, unpublished right now, where the NMR structure
of the monomer was determined and all other biochemical evidence
showed a monomer as the active form. The resulting crystal structure
turned out to be a domain swapped dimer. The group I did the work for
are still puzzling over it and have tried a number of things to see if
the structure is biologically significant.
