[Abstract]  One of the most compelling approaches in the discovery of novel antimicrobials is screening of natural sources. In our publication we report on the activity of a compound 8-hydroxyserrulat-14-en-19-oic acid (EN4), a diterpene isolated from the Australian plant Eremophila neglecta. We evaluate its applicability for treatment of implant-associated infections. A comprehensive analysis of the mechanism of action of EN4 against staphylococci revealed its membranolytic properties and a general inhibition of macromolecular biosynthesis, which was confirmed in a macromolecular biosynthesis ... [摘要]  在发现新的抗微生物剂中最引人注目的方法之一是筛选天然来源。在我们的出版物中,我们报告了一种化合物8-羟基胆固醇-14-烯-19-酸(EN4)(一种从澳大利亚植物中分离的二萜烯)的活性。我们评估其适用于植入物相关感染的治疗。对EN4对葡萄球菌的作用机制的综合分析揭示其膜分解性质和大分子生物合成的一般抑制,其在大分子生物合成测定中被证实并提出多靶点活性。用于研究EN4对肽聚糖,RNA,DNA和蛋白质的合成的影响的方法是基于大分子与三氯乙酸的沉淀。这些大分子由相应的[3 H] - 标记的前体合成。测量掺入和不掺入抗微生物剂的放射性,并反映测试化合物的作用模式。使用具有已知作用机制的抗生素作为对照。

[Abstract]  Many important regulatory proteins such as transcription factors are regulated through subcellular localization. Protein localization can be examined by fusing a GFP tag. However, GFP is relatively big in size, and potentially may affect correct protein localization. Several small tags have been developed, such as myc, HA or Flag. By using immunostain and fluorescence microscopy as described in this protocol, one can easily probe the regulation of a selected yeast protein with the application of the aforementioned small tags. [摘要]  很多重要调控蛋白如转录因子通过亚细胞定位调控。蛋白定位可以通过融和一个GFP标签来检测。尽管如此,GFP是相当的大的,可能作用于正确的蛋白定位。若干个小标签蛋白已经发展起来,如myc,HA或是Flag。通过使用以下描述的免疫染色和荧光显微镜方法,研究者们可以很容易的检测带有这些小标签酵母蛋白的调控。
