The cuticle of the silkworm Bombyx mori was demonstrated to contain pro-phenol oxidase [zymogen of phenol oxidase (monophenol, L-dopa:oxygen oxidoreductase, EC 1.14.18.1)] and its activating cascade. The activating cascade contained at least one serine proteinase zymogen (latent form of pro-phenol oxidase activating enzyme). When the extracted cascade components were incubated with Ca2+, the latent form of pro-phenol oxidase activating enzyme was itself activated and, in turn, converted through a limited proteolysis of pro-phenol oxidase to phenol oxidase. Immuno-gold localization of prophenol oxidase in the cuticle using a cross-reactive hemolymph anti-pro-phenol oxidase antibody revealed a random distribution of this enzyme in the nonlamellate endocuticle and a specific orderly arrayed pattern along the basal border of the laminae in the lamellate endocuticle of the body wall. Furthermore, prophenol oxidase was randomly distributed in the taenidial cushion of the tracheal cuticle. At the time of pro-phenol oxidase accumulation in the body wall cuticle, no pro-phenol oxidase mRNA could be detected in the epidermal tissue, whereas free-circulating hemocytes contained numerous transcripts of pro-phenol oxidase. Our results suggest that the pro-phenol oxidase is synthesized in the hemocytes and actively transported into the cuticle via the epidermis.
