Ag+-ATPase activity is measured as the difference between the activity in the medium with Ag+ and that measured in the same medium without Ag+ |

although the enzyme binds Cu+ with 15 times higher apparent affinity, Ag+ drives a faster turnover because the enzyme(Ag) form undergoes a faster dephosphorylation than the enzyme(Cu) form |

the enzyme is activated by Ag+ and to a lesser extent by Cu+. Maximum Cu+-ATPase activity is 25% of that measured in the presence of Ag+. However, Cu+interacts with the enzyme with higher apparent affinity. The activation by Ag+ or Cu+is dependent on the presence of millimolar amounts of cysteine. In the presence of ATP, these metals drive the formation of an acid-stable phosphoenzyme with apparent affinities similar to those observed in the ATPase activity determinations. Comparable levels of phosphoenzyme are reached in the presence of both cations. The stimulation of phosphorylation by the cations suggests that CopA drives the outward movement of the metal |
