微生物亚硝酸盐还原酶的研究进展

Research progress of microbial nitrite reductase

摘要:

亚硝酸盐还原酶(Nitrite reductase，简称NiR，EC1.7.2.1)是催化亚硝酸盐(Nitrite，简称NIT)还原的一类酶，可降解NIT为NO或NH3，是自然界氮循环过程的关键酶。本文详细阐述亚硝酸盐还原酶的分类、结构特点、催化机制以及现阶段的应用领域，为深入研究亚硝酸还原酶提供参考。

Abstract:

Nitrite reductase (NiR, EC1.7.2.1) is a kind of enzyme that catalyzes the reduction of nitrite (NIT). NiR is a key enzyme in the natural nitrogen cycle, which can degrade nitrite into NO or NH3. The classification, structural characteristics, catalytic mechanism and current application fields of nitrite reductase are reviewed in this report, which provides reference for further study of nitrite reductase.
