Through the method of initial heat release rate, the kinetic property of tyrosine oxidationcatalyzed by tyrosinase from Pseudomonas maltophilia was investigated using a LKB-2107 batchmicrocalorimeter. Tyrosine was catalyzed and oxidized into L-dopa, then into melanin catalyzed bytyrosinase. We found that the tyrosinase reaction obeyed the Michaelis-Menten kinetics, and at298.15K and pH 7.0, the initial exothermic rate (Ω₀) are in the range of0.1567~0.5704 mJ·s^-1, the maximum exothermic rate (Ω_max) are in 0.4152~0.8143mol·L^-1, and mean value of the Michaelisconstant (K_m) is 2.199±0.105×10⁴ mol·L^-1.
