  • 研究方向
  • (1)實驗室研發如何利用酵素生合成天然抗生素如Vitroprocines。我們目前發現其生合成反應機制需要兩個特別的酵素VsAOS-2和VsOR 來完成。除了生合成途徑,我們也專注於此類酵素在分子層次及三級結構之功能分析。此類抗生素可對抗多重抗藥性 Acinetobacter baumannii (鮑氏不動桿菌) 等在醫院常被感染之致病菌,如:肺炎、腦膜炎、皮膚組織感染及泌尿道感染。這項研究有助於新型抗生素研發。




  • (2)實驗室研究細胞膜蛋白如何進入生物膜的生理機制。大多數真核細胞膜蛋白質首先被插入內質網, 此過程稱為共同轉譯途徑 (co-translational pathway)。然而,有一類在生理功能上比較特別的膜蛋白,屬於尾端固定(tail-anchored, TA)膜蛋白家族,而是經由另一個稱為後轉譯途徑 (post-translational pathway) 的特殊新途徑完成。此途徑只有在真核細胞才有。錯誤的TA運送會導致癌症、糖尿病和心臟病等相關人類疾病。我們以真核物種為研究對象,探討TA 膜蛋白運如何被ArsAs (或Get3) 運輸蛋白送至各胞器外膜。這項研究對於TA 膜蛋白所引發的致病分子機制將有更進一步了解。
