It would be difficult because your protein probably affects the DNA conformation. Do you have some idea how your protein affects DNA conformation? But I think a brute force strategy trying every piece of DNA in the PDB as a template might work. Another approach would be to do MR using only segments of your DNA that might be straight B-DNA.

I am wondering 1) whether it is doable 2)if it is not doable, why not? Thanks in advance for the feedback
