异柠檬酸脱氢酶 (NAD+)(英语:isocitrate dehydrogenase (NAD+),EC 1.1.1.41 (页面存档备份,存于互联网档案馆))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:
异柠檬酸脱氢酶 (NAD+)需要二价锰离子(Mn2+)或二价镁离子(Mg2+)以维持活性。真核细胞中的异柠檬酸脱氢酶 (NAD+)以两种形式存在:其中一种与NAD+相关联且仅在线粒体中被发现并可以变构调节;另一种与NADP+还存在于细胞质基质中但不能变构调节。[2] 这两种酶——异柠檬酸脱氢酶 (NAD+)与异柠檬酸脱氢酶 (NADP+)并不相同,后者不能以草酰琥珀酸作为底物。某些物种的异柠檬酸脱氢酶 (NAD+)也能利用NADP+,但催化的反应速率较慢。[3]
