Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| 2-oxoglutaric acid | AKG, a reversible inhibitor of tyrosinase, inhibition kinetics integrated with molecular dynamics simulations reveal a complex induced parabolic slope mixed-type inhibition. AKG significantly inhibits the L-dopa oxidation of tyrosinase in a dose-dependent manner, complete inactivation at about 25 mM. Enzyme residues His85, His259, Asn260, Phe264, Met280, Gly281, and Val283 interact with the inhibitor | Agaricus bisporus |  |

| physiological function | tyrosinase is a multifunctional copper-containing metalloenzyme that is critical for melanin pigment production anddetoxification of phenol compounds. The catalytic roles of tyrosinase include multifunctional distinctions such as hydroxylaseand oxidase functions, and tyrosinase possesses catalase, peroxygenase, phenolase, and catecholase activities | Agaricus bisporus |
