Aggregation of Nucleosomes by Divalent Cations [PDF]
Biophysical Journal, 2001 Conditions of precipitation of nucleosome core particles (NCP) by divalent cations (Ca(2+) and Mg(2+)) have been explored over a large range of nucleosome and cation concentrations. Precipitation of NCP occurs for a threshold of divalent cation concentration, and redissolution is observed for further addition of salt. The phase diagram looks similar to

The modulation of TRPM7 currents by nafamostat mesilate depends directly upon extracellular concentrations of divalent cations [PDF]
Molecular Brain, 2010 Concentrations of extracellular divalent cations (Ca2+ and Mg2+) fall substantially during intensive synaptic transmission as well as during some pathophysiological conditions such as epilepsy and brain ischemia.

Divalent cations as modulators of neuronal excitability: Emphasis on copper and zinc [PDF]
Biological Research, 2006 Based on indirect evidence, a role for synaptically released copper and zinc as modulators of neuronal activity has been proposed. To test this proposal directly, we studied the effect of copper, zinc, and other divalent cations on voltage-dependent ...

How Divalent Cations Interact with the Internal Channel Site of Guanine Quadruplexes. [PDF]
Chemphyschem, 2021 The formation of guanine quadruplexes (GQ) in DNA is crucial in telomere homeostasis and regulation of gene expression. Pollution metals can interfere with these DNA superstructures upon coordination.

Activation of Deoxyribonucleases by Divalent Cations [PDF]
The Journal of General Physiology, 1962 The activation of DNase I by Mg, Mn, Co, Ni, Fe, Cd, Zn, Ba, Sr, Ca, and Cu ions has been studied by several methods, at different pH and salt concentrations. Mg, Mn, and Co are the best activators for initial stages of degradation. A synergistic effect is shown only by the pair Mg-Ca. Optimal pH of action is always situated at 6.5.

Adsorption of Divalent Cations on DNA [PDF]
Biophysical Journal, 2004 The distribution of divalent ions in semidilute solutions of high-molecular-mass DNA containing both sodium chloride and strontium chloride in near-physiological conditions is studied by small-angle x-ray scattering and by small-angle neutron scattering.

Transport of Divalent Cations [PDF]
Plant Physiology, 1979 The cation exchange capacity of the intact xylem vessels in cut shoots of papyrus (Cyperus papyrus spec.) has been determined. The cation exchange capacity is independent of the cation concentration in the transpiration stream, and is equal for Ca and Co.

Divalent cations influence AcrIIA22’s nicking activity.
, 2021 (A) We present the impact of different divalent cations on AcrIIA22’s nicking activity, which is highest with Mg2+, Mn2+, and Co2+. (B) The OC plasmid product persists through phenol-chloroform extraction following AcrIIA22 treatment, indicating that it ...
