氮(N)是氨基酸和核酸的重要组成部分，是生命的关键元素。大气（二氮，N2）和环境（硝酸盐和亚硝酸盐，NO3 -和NO2 -）来源的N要在各种生命形式的氨基酸合成中得到利用，首先必须还原为氨（NH3）。Haber-Bosch工艺是在高温高压下将N2还原为NH3的一种主要的NH3生产工艺，对农业作物工业产生了很大的影响。本文综述了全球生物地球化学N循环的三种关键酶（氮酶、硝酸还原酶和亚硝酸盐还原酶）的电化学研究进展，以期建立新的氨生产生物技术。
As an essential component of amino acids and nucleic acids, nitrogen (N) is a key element of life. For atmospheric (dinitrogen, N2 ) and environmental (nitrate and nitrite, NO3 - and NO2 - ) sources of N to be utilized in amino acid synthesis in various forms of life, it must first be reduced to ammonia (NH3 ). The Haber-Bosch process, in which N2 is reduced to NH3 at elevated temperature and pressure, represents a major NH3 production process that has had a great impact on the agricultural crop industry. This Minireview discusses the recent electrochemistry of three key enzymes of the global biogeochemical N cycle (nitrogenase, nitrate reductase, and nitrite reductase), in view of moving toward the creation of alternative NH3 production biotechnologies.
