My money is on: Dithiothreitol or dithioerythritol.
Any chance they are in there? If not and you believe this copurified with your protein, than I'd guess erythritol or threitol. (I didn't bother trying to gauge the stereochemistry from your picture) Cheers Andy On 4/2/09 1:38 PM, "Abhinav Kumar" <abhin...@slac.stanford.edu> wrote: > Hi, > > I am refining a structure and have a region of unmodeled density into > which I am trying to fit a ligand.
