If you need 3D-alignments of equal-length but different sequences,
the simplest is to use a RMS method on the backbone section.
One is described in J.Comput.Chem,1995,16[1],80-90.
If you need general 3D-alignments (no pairwise atomic correspondence is needed),
you can use the method described in J.Chem.Inf.Comput.Sci 1996,36[5],1038-1049.
I wrote the program. If you are looking for some collaboration, I can
perform the 3D-alignments and compute the maximal common 3D-substructure.
It works also for a family of more than 2 proteins.
