肽聚糖和细菌中几乎所有的表面糖聚合物都是在细胞质中的磷酸十一异戊二烯酯(UndP)脂质载体上构建的。这些Undp连接的前体被转运穿过膜并聚合或直接转移到表面聚合物、脂质或蛋白质。然后翻转UndP以再生面向胞质的UndP池。几十年来,催化运输的翻转酶的身份一直无法识别。在这里,使用针对UndP的抗生素两性霉素,我们发现了两个影响UndP循环的广泛保守的蛋白质家族。一个(UptA)是DedA超家族的成员;另一个(PopT)包含结构域DUF 368。遗传学、细胞学和同线性分析认为,这些蛋白质是缺失的UndP转运蛋白。重要的是,来自革兰氏阳性和革兰氏阴性细菌的同源物促进枯草芽孢杆菌中的UndP转运,表明回收活性在家族成员中广泛保守。这些翻转酶的抑制剂可以增强目前靶向细胞凋亡的抗生素。
Peptidoglycan and virtually all surface glycopolymers in bacteria are built in the cytoplasm on the lipid carrier undecaprenyl-phosphate (UndP). These UndP-linked precursors are transported across the membrane and polymerized or directly transferred to surface polymers, lipids, or proteins. UndP is then flipped to regenerate the pool of cytoplasmic-facing UndP. The identity of the flippase that catalyzes transport has eluded identification for decades. Here, using the antibiotic amphomycin that targets UndP, we discovered two broadly conserved protein families that affect UndP recycling. One (UptA) is a member of the DedA superfamily; the other (PopT) contains the domain DUF368. Genetic, cytological, and syntenic analyses argue that these proteins are the missing UndP transporters. Importantly, homologs from gram-positive and gram-negative bacteria promote UndP transport in Bacillus subtilis, indicating that recycling activity is broadly conserved among family members. Inhibitors of these flippases could potentiate the current arsenal of cell envelope-targeting antibiotics.
