一般說明

硝酸还原酶（NAD [P] H）在多种生物中表达，包括细菌、真菌、藻类和高等植物，它们具有使用硝酸盐作为其唯一氮源的能力。实验研究表明，硝酸还原酶（NAD [P] H））的大小为180,000道尔顿。

生化／生理作用

硝酸还原酶（NAD [P] H）可催化硝酸盐还原成亚硝酸盐。此外，它还可催化NADPH-细胞色素c、FADH2-硝酸盐的还原。硝酸还原酶还具有降低的甲基紫精-硝酸盐还原酶活性。

注意

光线和湿度敏感

單位定義

在存在 β-NADPH，pH7.6，37℃条件下，一个单位每分钟可还原 1.0 μmole 的硝酸盐。

Pyridine nucleotide-dependent nitrate reductases (NRs; EC 1.6.6.1-3) are molybdenum-containing enzymes found in eukaryotic organisms which assimilate nitrate. NR is a homodimer with an approximately 100 kDa polypeptide which folds into stable domains housing each of the enzyme's redox cofactors--FAD, heme-Fe

Barley (Hordeum vulgare L.) has NADH-specific and NAD(P)H-bispecific nitrate reductase isozymes. Four isogenic lines with different nitrate reductase isozyme combinations were used to determine the role of NADH and NAD(P)H nitrate reductases on nitrate transport and assimilation in barley seedlings.
