affects the physiology of unicellular organisms. As a continuation of our efforts toward the synthesis of OASS inhibitors, in this work we have used a combination of computational and spectroscopic approaches to rationally design, synthesize, and test a series of substituted 2-phenylcyclopropane carboxylic acids that bind to the two S. typhymurium OASS isoforms at nanomolar concentrations.
半胱氨酸是构成对生物至关重要的几种生物分子的基础。O催化半胱氨酸生物合成的最后一步-乙酰丝氨酸磺化酶(OASS)是高度保守的吡pyr醛5'-磷酸(PLP)依赖性酶,存在于细菌,植物和线虫的不同同工型中,但在哺乳动物中不存在。除了半胱氨酸的生物合成外,OASS还可以在细菌中发挥一系列“月光化”活动,例如转录调节,接触依赖性生长抑制,成群运动和诱导抗生素抗性。因此,发现能够抑制OASS的分子将是揭示该蛋白如何影响单细胞生物生理的有价值的工具。为了继续努力合成OASS抑制剂,在这项工作中,我们使用了计算和光谱方法相结合的方法来合理地设计,合成,鼠伤寒沙门氏菌OASS同工型在纳摩尔浓度。
