My question is how to use the radius of gyration, collapse term for a homodimer in the Xplor refinement script. Specifically, I'm interested in a domain swapped homodimer that has a very intertwined structure (but is still very globular). Do I only "assign" the residues in one subunit and then use double the expected radius of gyration? I am also using NCS symmetry in the refinement.
My current format is: collapse scale 1.0 assign (resid 3:66 ) 50.0 10.68 end Will this take the dimer into account, or should I double the expected radius of gyration to 21.4? Thanks, Theresa Department of Chemistry and Biochemistry, Miami University
