Abstract
Pentameric ligand-gated ion channels (pLGICs) of the Cys loop family are transmembrane glycoproteins implicated in a variety of biological functions. Here, we present a solution NMR study of the extracellular domain of a prokaryotic pLGIC homologue from the bacterium Gloeobacter violaceus that is found to be a monomer in solution.
摘要
五聚体配体门控离子通道（pLGICs）是 Cys 环家族的跨膜糖蛋白，参与多种生物学功能。在这里，我们报道了来自革兰氏阴性菌紫细菌的一种细菌 pLGIC 同源物的胞外结构域的溶液 NMR 研究，结果表明该同源物在溶液中为单体。
