固氮酶将N2 还原为NH3 的过程是自然界实现氮循环的重要环节。本文着重对固氮酶的固氮机理和其活性中心FeMo 辅基的人工模拟合成进行探讨, 其中包括FeMo蛋白中的质子和电子的传递, FeMo 辅基对N2 的活化方式,Mo 原子的作用, 固氮活性的测试。最后还就固氮酶的活性中心FeMo 辅基的人工模拟合成进行了探讨。

关键词： 固氮酶, 固氮机理, 固氮活性, FeMo辅基, 人工模拟合成

The process of nitrogen fixation in nitrogenase is an essential element for the nitrogen cycle in nature. In this article, the emphasisis on the mechanism of nitrogen fixation and the synthesis of manual simulation of FeMo-cofactor. Contents include: transfer of proton and electron in FeMo-protein,model of the dinitrogen activation by FeMocofactor, function of molybdenumatom in nitrogenase,measure for activity of nitrogen fixation. The synthesis of manual simulation of FeMocofactor is also discussed.

Key words: nitrogenase, mechanism of nitrogen fixation, activity of nitrogen fixation, FeMo-cofactor, synthesis of manual simulation
