蘋果酸脫氫酶 (草酰乙酸脫羧) (NADP+ ) (英語:malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+ ) ,EC 1.1.1.40 (頁面存檔備份 ,存於網際網路檔案館 ))是一種以NAD+ 或NADP+ 為受體 、作用於供體 CH -OH 基團 上的氧化還原酶 。這種酶 能催化 以下酶促反應 :
(S )-蘋果酸 + NADP+
⇌
{\displaystyle \rightleftharpoons }
丙酮酸 + CO2 + NADPH
蘋果酸脫氫酶 (草酰乙酸脫羧) (NADP+ )是C4 和CAM 植物 固定二氧化碳 過程中使用的三種脫羧酶之一(其餘兩種分別為蘋果酸脫氫酶 (脫羧) 和磷酸烯醇丙酮酸羧化激酶 )。[ 1] [ 2]
