Dear all, I am refining structures containing disulfides using refmac. Many of the disulfides are partly broken due to radiation damage.
I tried modeling alternative conformations (i.e. one cysteine pair in a disulfide and the other pair as free thiols), but after refinement the reduced form is forced back to its original position forming a disulfide bridge and resulting in difference density in the fo-fc map. How do I prevent a disulfide bond from being defined for the free thiol?
