The Cathodic Reduction of Zn (II) on the Zn and Au Electrode in the Zinc(II)–NH4Cl System
International Journal of Electrochemical Science, 2021 In recent years, the leaching of complex minerals containing zinc using the ammonia method has attracted much attention, but there are few basic studies of the cathodic reduction in the zinc(II)–NH4Cl system.

Biosorption of Zn(II) by Sphagnum Peat
Chemical Engineering Transactions, 2017 In this study, continuous up-flow fixed-bed column experiments were performed to investigate the biosorption potential of sphagnum peat to remove Zn(II) ions from aqueous solutions.

Zn(II) metabolism in prokaryotes [PDF]
FEMS Microbiology Reviews, 2003 It is difficult to over-state the importance of Zn(II) in biology. It is a ubiquitous essential metal ion and plays a role in catalysis, protein structure and perhaps as a signal molecule, in organisms from all three kingdoms. Of necessity, organisms have evolved to optimise the intracellular availability of Zn(II) despite the extracellular milieu.

Intracellular Zn(II) Intoxication Leads to Dysregulation of the PerR Regulon Resulting in Heme Toxicity in Bacillus subtilis. [PDF]
PLoS Genetics, 2016 Transition metal ions (Zn(II), Cu(II)/(I), Fe(III)/(II), Mn(II)) are essential for life and participate in a wide range of biological functions. Cellular Zn(II) levels must be high enough to ensure that it can perform its essential roles.

Role of Bound Zn(II) in the CadC Cd(II)/Pb(II)/Zn(II)-responsive Repressor [PDF]
Journal of Biological Chemistry, 2009 The Staphylococcus aureus plasmid pI258 cadCA operon encodes a P-type ATPase, CadA, that confers resistance to Cd(II)/Pb(II)/Zn(II). Expression is regulated by CadC, a homodimeric repressor that dissociates from the cad operator/promoter upon binding of Cd(II), Pb(II), or Zn(II).

Human Glyoxalase II Contains an Fe(II)Zn(II) Center but Is Active as a Mononuclear Zn(II) Enzyme [PDF]
Biochemistry, 2009 Human glyoxalase II (Glx2) was overexpressed in rich medium and in minimal medium containing zinc, iron, or cobalt, and the resulting Glx2 analogues were characterized using metal analyses, steady-state and pre-steady-state kinetics, and NMR and EPR spectroscopies to determine the nature of the metal center in the enzyme. Recombinant human Glx2 tightly
