摘　　要：乌头酸酶在三羧酸循环中催化柠檬酸生成异柠檬酸。本文以乌头酸酶为例,深入探讨了酶对对称底物分子进行选择的机理,同时对酶专一性分类系统进行了分析和重新调整。Aconitase is an enzyme that catalyzes the conversion of citric acid to isocitric acid in tricarboxylic acid cycle. Taking aconitase as an example in this paper, the mechanism of symmetric substrate molecule selected by enzyme was discussed thoroughly, and the classificatory system of enzyme specificity was analyzed and readjusted.
