[Biopython] Superpose structures

[Yasser Almeida Hernández]

Hi all!!

I want to superpose some structures on a reference one.
The fixed selection is the backbone atoms of two residues and i want  
to superpose the rest of structures based in this atoms (for the same  
residues in the others structures, of course)

Reference selection:
[[<Atom O>, <Atom C>, <Atom CA>, <Atom N>], [<Atom O>, <Atom C>, <Atom  
CA>, <Atom N>]]

The moving selection is a similar nested list, with the list of the  
residues backbone atoms to move in the query structures....

How can i superpose these structures based in the backbone atoms of  
two residues?

Please help me...
Thanks
