Hello, can you use the pisa server or similar to compare the extent of domain-domain and domain-DNA contacts versus crystal contacts in your structures? It might help to show which is the dominant factor affecting domain orientation.  Sent from Yahoo Mail on Android On Tue, 28 May 2019 at

It is very difficult to demonstrate rigorously that crystal packing does not favor a particular conformation. If you can show that the same conformation occurs in solution (SAXS, NMR), or that the same conformation is found in a different space group with different packing, then you have a

Hi All, I has recently solved my X-ray structures of the ZnF domains of protein and its complex with dsDNA. A structural comparison of holo-protein and the protein-DNA binary complex reveals that the relative orientation of domains ZnF3 undergoes a rotation of 50.5 degrees Does anyone know how
