加拿大SFU大學(Simon Fraser University)的研究團隊找到一種新方法對抗大腸桿菌(Escherichia coli, E. coli)及其他相關細菌所引起的感染。

大腸桿菌自然存在於人體腸道中,執行一些重要的消化任務。但有一種可能致命的大腸桿菌經常在變質或腐爛的食物中被發現,會攻擊人體的消化系統,導致食物中毒。

SFU大學分子生物及生物化學副教授Mark Paetzel及其學生Kelly Kim、Suraaj Aulakh發現兩種蛋白質結合在大腸桿菌的外膜。

這項研究近期發表於線上版的生物化學期刊(The Journal of Biological Chemistry)。研究題為「BAM複合體的晶體結構(Crystal structure of the β-barrel assembly machinery BamCD complex)」。...(詳全文)
