Abstract

In the presence of hydrogen peroxide cytochrome c can perform the oxidation of catecholamines and their S-cysteinyl-derivatives yielding melanins as final products. The initial reaction rate is linearly dependent on cytochrome c and H2O2 concentration; the reaction follows the Michaelis and Menten kinetics both for H2O2 and hydrogen donors. Sulfhydryl compounds inhibit the formation of the pigment. The reported dataindicate that a heme-containing protein belonging to the mitochondrial chain can accelerate the oxidation of catecholamines to eumelanins. (C) 1998 Elsevier Science Ltd.
