Details | The light scattering data of this construct without C-tag shows mainly monomeric protein in the solution, while the same construct with C-tag appears to have population of monomer and tetrameric species. Consistent with the latter observation, the crystal structure reveals that a few residues of the C-tag play an important role in protein tetramerization, which is possibly not a physiological phenomenon |
