Abstract

The enzyme activity of tyrosinase, catalase, peroxidase and the amount of metal ions in melanogenic subcellular compartments in pigment cells were measured. Tyrosinase and catalase were richest in coated vesicles whereas peroxidase . was found to be most prevalent in premelanosomes. The only metals which were detected in a significantly meaningful amount were copper, zinc and iron. These metals Were more concentrated in premelanosome than in coate dvesicle. A quantitative analysis revealed that peroxidase served to enhance eumelanin polymer formation from monomers with the co-existence of hydrogen peroxide and metal ions, especially, copper ions which had the greatest enhancing effect on the conversion of monomers to polymer.
