Functional and structural studies of a Phospholipase A2-like protein complexed to zinc ions: Insights on its myotoxicity and inhibition mechanism
(2017-01-01)
Background One of the main challenges in snakebite envenomation treatment is the development of stable, versatile and efficient anti-venom therapies. Local myotoxicity in accidents involving snakes from the Bothrops genus ...
Effect of membrane moiety and magnesium ions on the inhibition of matrix-induced alkaline phosphatase by zinc ions
(1990-01-01)
1. 1. The inhibition of matrix-induced alkaline phosphatase by zinc ions is due to the displacement of magnesium ions from its binding site. 2. 2. Binding of magnesium ions to alkaline phosphatase induces conformational ...
Polyoxyethylene 9-lauryl ether-solubilized alkaline phosphatase: Synergistic stimulation by zinc and magnesium ions
(1992-01-01)
1. 1. Polidocanol-solubilized apoalkaline phosphatase could be stimulated either by zinc ions (Kd = 8.5 nM) or by magnesium ions alone (Kd = 3.8 μM). 2. 2. Zinc and magnesium ions had synergistic effects on Polidocanol-solubilized ...
Zinc transport in mammalian cells
(American Physiological Society, 1996)
The importance of zinc in cell physiology is related mainly to its intracellular involvement in enzyme catalysis, protein structure, protein- protein interactions, and protein-oligonucleotide interactions. The mechanisms ...
Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...
