Structural and functional peculiarities of four types of nitrate reductases are considered: assimilatory nitrate reductase of eukaryotes, as well as cytoplasmic assimilatory, membrane-bound respiratory, and periplasmic dissimilatory bacterial nitrate reductases. Arguments are presented showing that eukaryotic organisms are capable of nitrate dissimilation. Data concerning new classes of extremophil nitrate reductases, whose active center does not contain molybdocofactor, are summarized.
真核生物的同化型硝酸还原酶，以及细胞质同化型、膜结合呼吸型和周质异化型细菌硝酸还原酶。文中提供了相关论据，表明真核生物具备硝酸盐异化作用的能力。同时总结了有关新型嗜极菌硝酸还原酶的数据，这类酶的活性中心不含钼辅因子。
