本文研究了在催化剂Ｌ型组氨酸衍生物催化下的丙氨酸硝基苯酚酯衍生物的水解反应，用ＺＩＮＤＯ程序对三个底物和两个催化剂的电荷分布和能量进行了计算．找出了催化活性中心，提出了合理的反应机理．
In this paper, the hydrolysis of the alanine-nitrophenol ester catalyzed by the L-histidine derivative was studied. The charge distribution and energy of the three substrates and the two catalysts were calculated using the ZINDO program. Find out the catalytic activity center, put forward a reasonable reaction mechanism.
