肽聚糖(PG)是一种保护细菌免受渗透裂解的多糖基质。抑制其生物发生是一种被证实的用抗生素杀死细菌的策略。PG的组装需要连接到聚异戊二烯脂质载体脂质II上的二糖五肽构建块。尽管脂质II合成的阶段是已知的,但将其转运到细胞质膜上进行PG聚合的必要翻转酶的身份尚不清楚。我们开发了一种检测脂质II翻转酶活性的方法,并使用化学遗传策略来快速特异性地阻断翻转酶的功能。我们结合这些方法来证明MurJ是大肠杆菌中的脂质II翻转酶。
Peptidoglycan (PG) is a polysaccharide matrix that protects bacteria from osmotic lysis. Inhibition of its biogenesis is a proven strategy for killing bacteria with antibiotics. The assembly of PG requires disaccharide-pentapeptide building blocks attached to a polyisoprene lipid carrier called lipid II. Although the stages of lipid II synthesis are known, the identity of the essential flippase that translocates it across the cytoplasmic membrane for PG polymerization is unclear. We developed an assay for lipid II flippase activity and used a chemical genetic strategy to rapidly and specifically block flippase function. We combined these approaches to demonstrate that MurJ is the lipid II flippase in Escherichia coli.
