高丝氨酸脱氢酶
高丝氨酸脱氢酶（英语：homoserine dehydrogenase，EC 1.1.1.3）是一种以NAD或NADP为受体、作用于供体CH-OH基团上的氧化还原酶。这种酶能催化以下酶促反应：
- L-高丝氨酸 + NAD(P)
L-天冬氨酸半醛 + NAD(P)H + H
高丝氨酸脱氢酶参与甘氨酸、丝氨酸和苏氨酸的代谢以及赖氨酸的生物合成。高丝氨酸脱氢酶参与天冬氨酸途径的第三步反应，在NAD或NADP的参与下将天冬氨酸半醛还原为高丝氨酸。

In enzymology, a homoserine dehydrogenase (EC1.1.1.3) is an enzyme that catalyzes the chemical reaction
The 2 substrates of this enzyme are L-homoserine and NAD (or NADP), whereas its 3 products are L-aspartate 4-semialdehyde, NADH (or NADPH), and H.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is L-homoserine:NAD(P) oxidoreductase. Other names in common use include HSDH, and HSD.
