at equilibrium two to three copper ions bind stoichiometrically to PK and destroy its activity. Initial reversible and weak binding phase and a slower, irreversible abolition of activity with a half-time of 6 min at saturating copper ion concentrations. PK digestion of cellular prion proteins and other proteins in brain homogenate is inhibited in a concentration-dependent manner at concentrations of more than 1 mM. Presence of calcium ions, up to 10 mM, has no effect on copper inhibition |
