Protein-cellodextrin complexes

Several of these geometries correspond to right-handed helices with between 2 and 3 residues per turn, but most lead to left-handed cellulosic structures. Further, this same majority has a distribution of positions that is very similar to that of the small molecule conformations and the conformations in the protein cellodextrin complexes. Whether the lactose-protein complexes are less accurately determined or there are special causes for the wider spread of the data is under study as this is written.

We do not know why the lactose-protein complex structures have a much wider range of conformations. At this time we cannot say that they are less accurately determined than the complexes of proteins and cellodextrins.
