糖基化是最复杂的翻译后蛋白质修饰之一。它的重要性已经确立,不仅对真核生物,而且对各种原核细胞过程,如生物膜的形成,运动和交配。然而,全面的糖蛋白组学分析在原核生物中很大程度上缺失。在这里,我们扩展了火山盐铁ax n -糖基化途径突变体的表型特征,并通过完整糖肽的质谱分析为这种模式古菌提供了详细的糖蛋白组。利用野生型(WT)和突变菌株的深入糖蛋白质组学数据集以及对古菌蛋白质组计划(ArcPP)数据集的重新分析,我们确定了迄今为止描述的最大的古菌糖蛋白质组。我们进一步证明,在相同的培养条件下,不同的n -糖基化途径可以修饰相同的糖基。外汇的范围和复杂性。本文揭示的火山n -糖蛋白组为研究n -糖基化在古细菌细胞生物学中的作用提供了新的见解。一项全面的火山盐铁酸盐糖蛋白组学分析揭示了古细菌糖基化的程度和复杂性,并为这种翻译后修饰在各种细胞过程中的作用提供了新的见解,包括细胞形状的决定。
Glycosylation is one of the most complex posttranslational protein modifications. Its importance has been established not only for eukaryotes but also for a variety of prokaryotic cellular processes, such as biofilm formation, motility, and mating. However, comprehensive glycoproteomic analyses are largely missing in prokaryotes. Here, we extend the phenotypic characterization of N-glycosylation pathway mutants in Haloferax volcanii and provide a detailed glycoproteome for this model archaeon through the mass spectrometric analysis of intact glycopeptides. Using in-depth glycoproteomic datasets generated for the wild-type (WT) and mutant strains as well as a reanalysis of datasets within the Archaeal Proteome Project (ArcPP), we identify the largest archaeal glycoproteome described so far. We further show that different N-glycosylation pathways can modify the same glycosites under the same culture conditions. The extent and complexity of the Hfx. volcanii N-glycoproteome revealed here provide new insights into the roles of N-glycosylation in archaeal cell biology. A comprehensive glycoproteomic analysis of Haloferax volcanii reveals the extent and complexity of glycosylation in archaea and provides new insights into the roles of this post-translational modification in various cellular processes, including cell shape determination.
