一氧化二氮还原酶（N2 OR）是呼吸链中的末端还原酶，其在分解细菌中将N2 O转化为N2：
{N_2}O + 2{H^ + } + 2{e^ - } \to {N_2} + {H_2}O$$
（[1]）
主要方面的主题已涵盖最近，这些评论可作为主要参考咨询。1，2高活性形式的酶从假单胞菌stutzeri（N2 OR I）有两个相同的亚基，每个携带混合价[Cu（1.5）... Cu（1.5）]，S = 1/2复合物。3酶的无催化活性衍生物（N2 OR V）也具有混合价EPR可检测位点。4，5
Nitrous oxide reductase (N2OR) is the terminal reductase in a respiratory chain converting N2O to N2 in the denitrifying bacteria:
$${N_2}O + 2{H^ + } + 2{e^ - } \to {N_2} + {H_2}O$$
([1])
Principal aspects of the subject have been covered recently, and these reviews may be consulted for primary reference.1,2 The high activity form of the enzyme from Pseudomonas stutzeri (N2OR I) has two identical subunits, each carrying a mixed-valence [Cu(1.5)...Cu(1.5)], S = 1/2 complex.3 A catalytically inactive derivative of the enzyme (N2OR V) has also the mixed-valence EPR-detectable site.4,5
