一般說明

卷心菜磷脂酶D(PLD)包含C2结构域和带HxKx4Dx6GSxN(HKD)基序的PLD超家族特异性保守区域(I–IV)。[1]结构上是一种连接钙离子的桶状单体。[1]

應用

在荧光标记脂质制备过程中，该酶已可用于制备氟硼吡咯-磷脂酰胆碱。[2]
磷脂酶D(PLD)水解磷脂与鞘磷脂的磷酸键，得到相应的磷脂酸。它已可用于研究代谢标记和 体内 直接成像胆碱磷脂，通过测量propargyl-cho的掺入[3]。 此外，PLD已可用于纯化和动力学研究[4]。

生化／生理作用

卷心菜磷脂酶D(PLD)的氨基酸序列与拟南芥PLDα和蓖麻子PLD的一致性分别为83%和80%[5]。 磷脂酶D水解磷脂和鞘磷脂的磷酸键，从而得到相应的磷脂酸。
水解磷脂和鞘磷脂的磷酸键，获得相应的磷脂酸。
磷脂酶D（来源于卷心菜）广泛用于生物催化的转磷脂酰反应。[6]
