The genetic polymorphisms due to mutations in the methylene tetrahydrofolate reductase gene may increase the risk for ntds 亚甲基四氢叶酸还原酶基因突变导致的遗传多态现象可增加神经管缺陷( ntd )发生的危险性。
Nitric oxide can be produced in plant cells via animal no synthase ( nos ) or nitrate reductases and through nonenzymatic reactions 摘要植物体可以通过依赖于类似哺乳动物的一氧化氮合成酶或硝酸还原酶的酶促合成途径和非酶促合成途径产生一氧化氮。

P450nor is a nitric oxide ( no ) reductase ( nor ) found in eukaryotic microorganisms , which reduces no to nitrous oxide ( n2 o ) by directly accepting electrons from nadh or nadph 细胞色素p450nor起着一氧化氮还原酶的作用，能以nad ( p ) h为直接电子供体将no还原成n _ 2o 。
Besides , it shows significant correlation ( r > 0 . 82 ) among the growth characteristics and the concentration of nitrate reductase , as well as soluble protein among the provenances 除此之外，生长特性、硝酸还原酶含量和可溶性蛋白含量之间有显著相关性，相关系数均在0 . 82以上。
Finasteride , an inhibitor of 5alpha - reductase , inhibits the conversion of testosterone to dihydrotestosterone , the primary androgen in the prostate , and may reduce the risk of prostate cancer 作为一种5 -还原酶的抑制剂，非那斯提可以阻止睾酮转化为双氢睾酮（前列腺内最主要的雄激素） ，所以可能会降低前列腺癌的发病率。

It also has great change in the concentration of nitrate reductase among the provenance no matter when is in april of the dormancy period or in june of the growing period , with the same change trend for the same provenance 无论是生长期( 6月份)还是休眠期( 4月份)各种源间硝酸还原酶浓度都有很大差异，即生长快的种源硝酸还原酶浓度也高，反之则低。
Nitrate is converted to ammonium by nitrate reductase and ammonium is then incorporated into glutamine and gluamate , either by the glutamine synthase - glutamate synthase ( gs - gogat ) pathway or by glutamate dehydrogenase ( gdh ) 硝酸盐在硝酸还原酶作用下被转化为铵，接着所产生的铵在谷氨酰胺合成酶-谷氨酸合酶( gs - gogat )或谷氨酸脱氢酶( gdh )的作用下与谷氨酰胺和谷氨酸结合。
