固氮酶是一个含金属钼和铁的蛋白质。在催化还原分子氮及其他底物的过程中,是钼还是铁,或者钼和铁同时与底物首先络合,是迄今尚未阐明的问题。在第二次全国化学模拟生物固氮交流会上,我们曾报道二氯四呲啶铁在溶液中催化还原叠氮化物为氨的活性受外加钼酸钠的促进。进一步的实验表 Nitrogenase is a metal containing molybdenum and iron protein. In the catalytic reduction of molecular nitrogen and other substrates in the process of molybdenum or iron, or molybdenum and iron at the same time the first complex with the substrate is so far not yet clarified. At the Second National Chemical Simulation of Biological Nitrogen Fixation Symposium, we reported that the activity of dichloro-tetrabromine in the catalytic reduction of azide to ammonia in solution was promoted by the addition of sodium molybdate.
