Abstract
A sulfide surprise: The analysis of ZnII-, CdII-, and CuI-MT recombinant preparations of metallothioneins (MTs) from many organisms provides clear evidence that sulfide ions are present in nearly all their physiologically stable ZnII-MT and CdII-MT complexes (see picture), but in none of the CuI-MT species. The features of the MT complexes are in good correla(Chemical Equation Presented) tion with those reported for plant and yeast ZnII- or CdII-γ- glutamyl peptides. © 2005 Wiley-VCH Verlag GmbH & Co.
