WebCrystal structures of NiII and CuII-supplemented TriCyt1 revealed a biologically rare His6 coordination motif. The only known natural His6 motif is present in calprotectin, a metal sequestering protein that coordinates MnII with nanomolar affinity. WebThe structures of pure metals are easy to describe because the atoms that form these metals can be thought of as identical perfect spheres. The same can be said about the structure of the rare gases (He, Ne, Ar, and so …
WebSediments originating from periodic waterways dredging were traditionally deposited on soil without specific precaution or planed treatments. It may be of environmental concern especially when they came from historically heavy metals¬contaminated areas (zinc, lead) like north French coal basin.
