title: On the copper transfer between dopamine beta-monooxygenase and Cu-thionein.
abstract: Metallothionein saturated with copper is able to donate copper to apodopamine beta-monooxygenase. The complete recovery of dopamine beta-monooxygenase activity is observed at the molar ratio Cu-thionein/apoenzyme of 25. On the other hand, apothionein accepts copper easily from the holoenzyme.
