There are different zinc coating technologies for corrosion protection of metal surfaces. The most widespread methods are hot dip galvanizing (zincing by dipping items into melted zinc) and electrolytic method by zinc deposition from the electrolytic solution (electroplating). The process of thermo-diffusion of a zinc coating is a newer process that forms a zinc alloy with the substrate. The US...

Streptococcus pneumoniae is a globally significant pathogen that causes a range of diseases, including pneumonia, sepsis, meningitis, and otitis media. Its ability to cause disease depends upon the acquisition of nutrients from its environment, including transition metal ions such as zinc. The pneumococcus employs a number of surface proteins to achieve this, among which are four highly similar...

Zinc is indispensable to all forms of life as it is an essential component of many different proteins involved in a wide range of biological processes. Not differently from other metals, zinc in proteins can play different roles that depend on the features of the metal-binding site. In this work, we describe zinc sites in proteins with known structure by means of three-dimensional templates tha...

This study compared the minimal inhibition concentrations (MICs) and their effects on growth kinetics of seven different types zinc (Zn) compounds Na2EDTA in case three typical commensal beneficial microorganisms (Bacillus subtilis, Lactococcus lactis, Saccharomyces cerevisiae). The Zn included ZnSO4, four Zn–amino acid chelates, two Zn–EDTA complexes. Both MICs kinetic parameters indicated tha...

Recycling is extremely important for steelmaking. In developed countries, about 60% of steel is manufactured from scrap. The scrap contains 0.5% of zinc in average, and this percentage steadily increases. During the steelmaking process both in basic oxygen furnaces (BOF) and in electric arc furnaces (EAF), all volatile zinc is released and forms airborne particles of dust. About 20 kg of dust i...

This study was undertaken to further establish the nature of the low molecular weight metal-binding proteins in rat testes. In all cases, control testes were compared to livers of zinc-treated rats, which are known to contain high concentrations of metallothionein. Gel filtration of testicular and hepatic cytosol revealed a major zinc- and/or cadmium-binding protein in the low molecular weight ...

Recombination-activating gene 1 (RAG1), as well as RAG2, are the only lymphoid-specific genes required for V(D)J recombination. RAG1 protein contains a C3HC4 zinc-binding motif (zinc ring finger) that binds two zinc ions. We have found that RAG1 contains additional zinc-binding motifs in the form of two separate C2H2 zinc finger sequences. One of the zinc fingers, in combination with the C3HC4 ...
