全反式视黄醇脱氢酶 (NAD+)(英语:all-trans-retinol dehydrogenase (NAD+)EC 1.1.1.105页面存档备份,存于互联网档案馆)),是一种以NAD+NADP+受体、作用于供体CH-OH基团上的氧化还原酶。这种催化以下酶促反应

全反式视黄醇-视黄醇结合蛋白 + NAD+ 全反式视黄醛-视黄醇结合蛋白 + NADH + H+

全反式视黄醇脱氢酶 (NAD+)能以全反式视黄醇和全反式视黄醛底物,且对NAD+/NADH辅因子有很强的特异性。这种酶既能识别处于游离态的底物也能识别与视黄醇结合蛋白相结合时的底物,但对结合状态下的底物具有更高的亲和性。[1]
