Abstract

is a frequent bacterial pathogen of the human respiratory tract causing pneumonia, meningitis and sepsis, a serious healthcare burden in all age groups. lacks complete respiratory chain and relies on carbohydrate fermentation for energy generation. One of the essential components for this includes the mannose phosphotransferase system (Man-PTS), which plays a central role in glucose transport and exhibits a broad specificity for a range of hexoses. Importantly, Man-PTS is involved in the global regulation of gene expression for virulence determinants. We herein report the three-dimensional structure of the EIIA domain of mannose phosphotransferase system (SpEIIA-Man). Our structure shows a dimeric arrangement of EIIA and reveals a detailed molecular description of the active site. Since PTS transporters are exclusively present in microbes and sugar transporters have already been suggested as valid targets for antistreptococcal antibiotics, our work sets foundation for the future development of antimicrobial strategies against .

摘要

是一种常见的人类呼吸道细菌病原体,可引起肺炎、脑膜炎和败血症,在所有年龄段都是严重的医疗保健负担。 缺乏完整的呼吸链,依赖碳水化合物发酵来产生能量。其中一个重要组成部分是磷酸甘露糖转移酶系统(Man-PTS),它在葡萄糖转运中起着核心作用,并表现出对一系列己糖的广泛特异性。重要的是,Man-PTS 参与了毒力决定因素的全局基因表达调控。我们在此报告了 甘露糖磷酸转移酶系统(SpEIIA-Man)的 EIIA 结构域的三维结构。我们的结构显示了 EIIA 的二聚排列,并揭示了活性位点的详细分子描述。由于 PTS 转运蛋白仅存在于微生物中,并且糖转运蛋白已被提议作为抗链球菌抗生素的有效靶点,因此我们的工作为未来针对 的抗菌策略的发展奠定了基础。
