Identification Of Heavy Metal Transporters
… heavy metal detoxification mechanisms, the phytochelatin dependent pathway plays an essential role in detoxification and sequestration of heavy metals in plants, fungi and some nematodes. While the mechanism of phytochelatin biosynthesis has been well established, proteins mediating …

Untersuchungen zur Zusammensetzung, Stabilität und Struktur von Cadmiumkomplexen mit biologisch und medizinisch relevanten Liganden
… von Cd(II) mit Glutathion (gamma-Glu-Cys-Gly), Phytochelatin 2 (gamma-Glu-Cys-gamma-Glu-Cys-Gly) und meso-2,3-Dimercaptobernsteinsäure, sowie die Protonierungskonstanten dieser Liganden bestimmt. Die experimentelle Vorgehensweise, wie auch die Auswertung mit dem Programm BEST wurden ausführlich …

Effects of copper on calcium metabolism and detoxification mechanisms in freshwater bivalve species of Anodonta
… suggest that metal-detoxification is induced. Phytochelatins (PC) are Cys-rich oligopeptides synthesised by phytochelatin synthase from glutathione in plants and fungi. Phytochelatin synthase genes have recently been identified in invertebrates; this allows us to hypothesize a role of PC in …

Synthesis of Water Soluble Quantum Dots and their Application for Enzymatic Activity Measurements
… solubility of QDs. It is only applicable for phytochelatin-related peptides, not for all kind of peptides. The co-coupling peptide and PEG on QDs, has good water-solubility when the quantity of PEG and coupling agent EDAC are controlled. The enzymatic activities based on QDs FRET system at …

Production of Copper-Complexing Ligands in Response to Elevated Concentrations of Copper in Marine <i>Synechococcus</i> spp.
… The intracellular CBC was shown not to be MT, phytochelatin or a siderophore. It is not a peptide; it contains lysine and an unidentified UV 254-absorbing component. This compound is a novel copper-binding ligand previously not reported in <em>Synechococcus </em>spp. and may function as a …

Innovative technologies of phytoremediation for contaminated soils
… the synthesis of sulfur-rich ligands such as phytochelatins, a cysteine-rich oligopeptide, that strongly bound metals. The presence of As upregulated the production of these specific proteins/ligands that bound and traslocated Cd into the plant tissue suggesting that the two metals interacted …
