The effects of errors in Km and Vmax. on the determination of the kinetic constants for the irreversible inhibition of acetylcholinesterase were determined. The results show that small errors in the values of Km and Vmax. give rise to large errors in the fitted parameters k2 and Kd. The problem may be minimized for multiple progress curves by selecting an appropriate number and distribution of inhibitor concentrations.
测定了Km和Vmax误差对不可逆抑制乙酰胆碱酯酶动力学常数测定的影响。结果表明,Km和Vmax值的微小误差会导致拟合参数k2和Kd出现较大误差。通过选择合适数量和分布的抑制剂浓度,对于多条进程曲线,该问题可能会最小化。
