[Abstract]  Plant transformation and exogenous protein expression is essential for molecular biology and biotechnology. Current approaches of stable plant transformation might be problematic and very time-consuming. Because of this, transient expression in protoplasts has become valuable alternative, being less cost and time-effective at the same time. Excellent for eukaryotic proteins, representing a natural cell habitat, protoplast isolation is widely used in protein interaction visualization techniques, like BiFC (Bimolecular fluorescence complementation) and FRET (Förster resonance energy transfer). ... [摘要]  植物转化和外源蛋白质表达是分子生物学和生物技术的必要条件。 目前稳定植物转化的方法可能有问题且非常耗时。 因此,在原生质体中的瞬时表达已经成为有价值的替代方案,同时成本更低和时间有效。 优异的真核蛋白,代表天然细胞栖息地,原生质体分离广泛应用于蛋白质相互作用可视化技术,如BiFC(双分子荧光互补)和FRET(弗尔斯特共振能量转移)。 在本协议中,我们提出了在蛋白质降解测定中使用拟南芥原生质体,证明其作为蛋白质组学工具的高度通用性。

[Abstract]  Acid phosphatases (APases) catalyze the hydrolysis of inorganic phosphate (Pi) from a broad range of Pi-monoesters with an acidic pH optimum. The liberated Pi is reassimilated into cellular metabolism via mitochondrial or chloroplastic ATP synthases of respiration or photosynthesis, respectively. Eukaryotic APases exist as a wide variety of tissue- and/or cellular compartment-specific isozymes that display marked differences in their physical and kinetic properties. Increases in intracellular (vacuolar) and secreted APase activities are useful biochemical markers of plant nutritional Pi ... [摘要]  酸性磷酸酶(APase)催化来自具有酸性pH最佳值的宽范围的P 1 - 单酯的无机磷酸盐(P 1)的水解。 释放的Pi分别通过呼吸或光合作用的线粒体或叶绿体ATP合酶再吸收到细胞代谢中。 真核APase作为多种组织和/或细胞区室特异性同工酶存在,其在它们的物理和动力学性质上显示出显着的差异。 细胞内(液泡)和分泌的APase活性的增加是植物营养缺乏的有用的生物化学标记物。 提出了蛋白质提取,APase活性测定和来自植物组织或细胞悬浮培养物的可溶性蛋白质浓度的测定方案。
