The kinase transfers the phosphate from an autophosphorylated histidine and thus (why thus?) is often reversible, with the kinase acting as a phosphatase as well.

这个激酶从自我磷酸的组氨酸上转移磷酸基，因此（为什么是这样）通常是可逆的，这个激酶也作为一个去磷酸酶。

The results showed that exogenous ethylene could increase ethylene production by 420% and 73%, reduce the activity of NAD kinase by 20% and 40% and had no obvious effects on NADP phosphatase activity.

结果表明，外源乙烯能诱导草莓果实乙烯大量合成，比对照（未经任何处理）提高420%和73%，抑制NAD激酶活性约20%和40%，对NADP磷酸酶影响不明显。
