Copper has been progressively removed from dopamine-β-hydroxylase by incubation with chelex resin. The relationship between the activity (A) and the copper/protein ratio (r) has been shown to be of the form Ar2 which implies that the enzyme catalysed reaction is second order with respect to protein bound copper. These results support a model for the catalytic mechanism involving binuclear copper sites rather than the four copper atoms in the enzyme acting independently.
