Binding of Cd2+ and Zn2+ with the Phytochelatin (γ‐Glu‐Cys)4‐Gly: A Voltammetric Study Assisted by Multivariate Curve Resolution and Electrospray Ionization Mass Spectrometry

“…This implies not only some methodological adaptations of the original method but also some conceptual changes in data interpretation [13,14]. MCR-ALS has been applied to several voltammetric techniques, including cyclic voltammetry [15], and to a variety of metal complex systems such as those of Cd 2þ and Zn 2þ with a-and b-metallothionein (MT) domains [16], PC 2 [8] and PC 3 [17].…”

Does chemometrics enhance the performance of electroanalysis?

“…This allowed the resolution of the Cd 2+ /Cys-Gly system with the aid of MCR-ALS [142]. The metal-phytochelatin interactions were studies with the use of DPV [143], while the binding properties of Cd 2+ -GSH were investigated by CV [144], and the results were resolved by MCR-ALS. The complexation between Zn 2+ and GSH and their fragments ␥-Glu-Cys and Cys-Gly were studied by DPP and again with the aid of MCR-ALS [145,146].…”

Adsorptive accumulation in constant current stripping chronopotentiometry as an alternative for the electrochemical study of metal complexation by thiol-containing peptides

“…(c-GluCys) 2 Gly was synthesized in the Institute of Organic Chemistry and Biochemistry, AS CR, Prague. The Merrifield method [28] with procedure modification described in [15] was applied. For measurements, freshly prepared solutions of peptide in borate buffer pH 8.5 were used.…”

“…Polarographic and voltammetric techniques, especially in differential pulse mode (DPP or DPV), have been widely used for the study of heavy metal complexes of thiol-containing peptides as GSH [8][9][10][11][12] or PCs [13][14][15]. In general terms, they produce intrincate sets of overlapping signals corresponding to the reversible reduction of the free metal ion, the irreversible reduction of strongly bound metal ions and some oxidation processes of mercury.…”
