title: Intramolecular electron transport in human ferroxidase (caeruloplasmin).
abstract: The oxidation of reduced human ferroxidase by molecular O2 was studied in a stopped-flow spectrophotometer. It was shown that the two type 1 copper atoms behave differently in the absence of iron. The effect of iron on the kinetic parameters was investiagted. A working model for intramolecular electron transport in the enzyme is proposed.
