Cupric Cation

supplement:

Magnesium Cation

Research Papers that Mention the Interaction

The enzyme had maximal activity in the presence of Mg2+ (40 muM) and Mg2+ (4 mM) stabilized the enzyme at 37 degrees C. Cupric ion (0.5 mM) inhibited (50%) enzyme activity in the presence or absence of Mg2+.

The result showed that Mg(II) has weaker binding capacity with the drug comparing Cu(II) , but both Mg(II) and Cu(II) can obviously reduce the binding constant of DNA with the drug.

Zn++, Ni++, Cu++ , Fe++, Sn++ and Hg++, in the presence of 5mM Mg++ , inhibited cAMP PDE activity whereas these divalent metal ions alone did not affect enzyme activity if Mg++ were absent.

It is established that Ca++ activates, and Fe++ has not effect on the activity of acid and alkaline DNases, while Mg++ , Mn++ and especially Co++, Zn++, Cd++, Cu++ have an inhibitory effect on them.

The presence of Mg2+ , Ca2+ and Ba2+ cations strongly activated the enzyme; however, Cu2+ and Zn2+ cations had inhibitory effects on the enzymatic activity.
