Web4,4′-Dithiodipyridine (dtdp), also termed 4,4′-dipyridyldisulfide, is a bridging ligand of the 4,4′-bipyridine type. The introduction of the disulfide moiety inevitably leads to a relatively rigid angular structure, which exhibits axial chirality. More than 90 metal complexes containing the dtdp ligand have been crystallographically characterised until now. WebAug 13, 2015 · The protein NEIL-1 is an example of how disorder prediction can be utilized to target structural studies; originally the authors had attempted crystallisation of the full length sequence .
