The phenol oxidase systems of Drosophila melanogaster arise from at least four protein components. One A component plus the P preparation yields tyrosinase, while the other two (A2 and A3) yield primarily 3,4-dihydroxyphenylalanine oxidases. Probably the four components represent specialized subunits of the oxidases produced.
