Extracellular tyrosinase from the fungus Trichoderma reesei shows product inhibition and different inhibition mechanism from the intracellular tyrosinase from Agaricus bisporus

► Trichoderma reesei tyrosinase suffers from dopachrome product inhibition. ► Sodium azide forms azido-quinone adducts with the tyrosinase reaction end products. ► Potassium cyanide and kojic acid are strong inhibitors of T. reesei tyrosinase.
