General description
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。
Biochem/physiol Actions
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。
Other Notes
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。

The FNR (fumarate and nitrate reductase regulation) protein of Escherichia coli is an oxygen-responsive transcriptional regulator required for the switch from aerobic to anaerobic metabolism. In the absence of oxygen, FNR changes from the inactive to the active state. The

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
