Our models were all generated as monomers---we were very lucky that
the arm that extends out to the dimeric partner (approx R101-F121) did
not move much in optimization, as we had no tools to constrain it to
fit on the end of the sheet of the dimeric partner.

The biggest differences between our alignments are what is done with
the N-terminus---how it is packed out of the way of the dimerization.
We tried various hand-created constraints to move it out of the way.
