Possible Interaction: Magnesium Chloride and Potassium Chloride

“Adding KCl in the presence of MgCl2 increased binding, with aK0.5 for KCl near 0.5 mM; the increased binding was associated with a drop inKd for vanadate to 11 nM but with no change in maximal binding.”

“Increasing potassium chloride concentration from 0 to 100mM and magnesium chloride from 0 to 2mM show a parallel rate increase in polymerizing actin, whereas increasing calcium chloride concentration from 0 to 0.2mM decreases the rate of polymerizing actin.”

“Pretreatment of the dentinal cavity with CaCl2, MgCl2 or SrCl2 greatly reduced the response of intradental nerves to KCl.”

“Voltage-clamp experiments on single frog (Rana pipiens) atrial cells using whole cell recording techniques revealed that the addition of MgCl2 to the 150 mM KCl patch pipette solution influenced the voltage- and time-dependent potassium current (IK).”

“Our results show that thick filaments dissociate from both ends on increasing the KCl concentration in the presence of 10 mM pyrophosphate and 5 mM MgCl2.”

“ MgCl2 and spermine also interfered with the effect of KCl.”

“The protein factor inhibited the rate and the extent of actin polymerization under nearly physiological conditions (for example, in 3 mM MgCl2 plus 90 mM KCl at pH 6.8).”

“ KCl decreased AMP-PNP binding in the presence or absence of MgCl2 , but the simultaneous presence of a molar excess of NaCl abolished (or masked) the effect of KCl.”

“Addition of KCl to the enzyme before the addition of ATP plus MgCl2 resulted in a low rate and extent of phosphorylation.”

“The RNAse eluted from CM-cellulose at 0.075 M KCl was almost completely inhibited by anti-RNAse A serum and by the endogenous RNAse inhibitor and a 33% inhibition was observed in the presence of 5 mM MgCl2.”
