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 ...

Arresting an Unusual Amide Tautomer Using Divalent Cations
, 2019 Ion-specific effects on peptides and proteins are key to biomolecular structure and stability. The subtle roles of the cations are far less understood, compared to the pronounced effects of the anions on proteins.

Fluorescent Protein-Based Ca2+ Sensor Reveals Global, Divalent Cation-Dependent Conformational Changes in Cardiac Troponin C. [PDF]
PLoS ONE, 2016 Cardiac troponin C (cTnC) is a key effector in cardiac muscle excitation-contraction coupling as the Ca2+ sensing subunit responsible for controlling contraction. In this study, we generated several FRET sensors for divalent cations based on cTnC flanked

Boron adsorption in semiarid Mediterranean soils under the influence of background electrolytes [PDF]
Global Journal of Environmental Science and Management, 2022 BACKGROUND AND OBJECTIVES: Boron is a micronutrient of high importance, both for plant development and normal growth. The range between boron deficiency and toxicity is very narrow, which makes boron unique among the essential micronutrients.

The regulation of integrin function by divalent cations [PDF]
Cell Adhesion & Migration, 2012 Integrins are a family of α/β heterodimeric adhesion metalloprotein receptors and their functions are highly dependent on and regulated by different divalent cations. Recently advanced studies have revolutionized our perception of integrin metal ion-binding sites and their specific functions.

The binding of divalent cations to myosin
Journal of Biological Chemistry, 1975 Centrifuge transport, equilibrium dialysis, and electron paramagnetic resonance studies on the binding of Mn2+ to myosin revealed two sets of noninteracting binding sites which are characterized at low ionic strength (0.016 M KCl) by affinity constants of 10(6) M-1 (Class I) and 10(3) M-1 (Class II), respectively.
