• PubMed Abstract: 
  

  The medicinal gold(III) dithiocarbamato complex AuL ₁₂ forms a stable adduct with bovine serum albumin. The crystal structure reveals that a single gold(I) center is bound to Cys34, with the dithiocarbamato ligand being released. To the best of our knowledge, this is the first structure for a gold adduct of serum albumin.
