Melanogenesis in Cryptococcus neoformans

J Gen Microbiol. 1988 Apr;134(4):1037-41. doi: 10.1099/00221287-134-4-1037.

Abstract

Melanogenesis in Cryptococcus neoformans begins with the oxidation of dihydroxyphenylalanine by the enzyme phenol oxidase. The succeeding steps are very rapid. Two intermediates, dopachrome and 5,6-dihydroxyindole, have been isolated and characterized by high performance liquid chromatography. A pathway of melanin formation in C. neoformans is proposed, based on the presence of these intermediates.
