Consuming mushrooms that contain tyrosinase and melanin antigens could influence a humoral anti-melanoma immune response, according to a study. Researchers studied 63 patients with melanoma ...

From mushroom to the walnut leaf . The tyrosinase, which is a metal-containing enzyme catalysing the oxidation of phenols, has been explored by Annette Rompel for over 20 years.

Their assays utilized tyrosinase from the mushroom Agaricus bisporus to confirm inhibition. Subsequent experiments pinpointed the active compound as cyclo(L-Pro-L-Tyr).

Also, human tyrosinase is difficult to extract as it’s bound to the membrane in skin cells — unlike mushroom tyrosinase, which is a free-floating protein and easy to isolate.
