Glucose inhibition of β-glucosidases. The initial rates of the hydrolysis of 5 μM MUG by TaBG3 (A), 2.5 μM MUG by AtBG3 (B) or 50 μM pNPG by N188BG (C) measured in the presence of glucose (v_i) were divided by those measured in the absence of glucose (v₀). The temperatures used were 25°C (□), 35°C (■), 45°C (◊), 55°C (♦) and 65°C (∆). The solid lines are from the non-linear regression according to Equation 3.
