一般說明
磷脂酰丝氨酸(PS) 是一种膜磷脂,富含于质膜的胞质小叶中。它包含总磷脂的2-10%。NBD PS是一种荧光标记的磷脂,在PS的头基上带有7-硝基苯-2-氧杂-1,3-二氮杂-4-基(NBD)。
應用
16:0-06:0 NBD PS已被用作标记的转位酶,以检测跨晚期高尔基体膜的ATP依赖性转位。它还适用于分析蛋白脂质体中的磷脂促翻转酶1(PLSCR1)加扰,并确定脂磷壁酸合酶(LtaS)的酶特异性。
16:0-06:0 NBD PS或1-棕榈酰基-2-{6-[(7-硝基-2-1,3-苯并恶二唑-4-基)氨基]己酰基}-sn-甘油-3-磷酸丝氨酸(铵盐)已用于7-硝基苯-2-氧杂-1,3-二唑-4-基(NBD)−磷脂酶(PL)易位测定中,以鉴定酵母高尔基体膜中ATP依赖的翻转酶活性。它可以用于:检测水泡性口炎病毒G(VSV G)蛋白介导的细胞-细胞融合,测量脂质体中脂磷壁酸(LTA)合酶(LtaS)的酶底物特异性,以确定磷脂促翻转酶1(PLSCR1))在磷脂加扰中的作用。
生化/生理作用
磷脂酰丝氨酸(PS)参与许多酶和结构成分的调节。它是清除凋亡细胞的重要因素。它与阿尔茨海默氏′病的认知障碍有关。

Lipoteichoic acid (LTA) is an important cell wall polymer in Gram-positive bacteria. The enzyme responsible for polyglycerolphosphate LTA synthesis is LtaS, first described in Staphylococcus aureus. Four LtaS orthologues, LtaS(BS) , YfnI, YqgS and YvgJ, are present in Bacillus subtilis.

Lipoteichoic acid (LTA) is an important cell wall component of Gram-positive bacteria. The key enzyme responsible for polyglycerolphosphate lipoteichoic acid synthesis in the Gram-positive pathogen Staphylococcus aureus is the membrane-embedded lipoteichoic acid synthase enzyme, LtaS. It is presumed that LtaS
