翻译后糖基化是真核生物、古细菌和细菌中普遍存在的蛋白质修饰。最近发表的两篇文章首次证实了人类胃肠道病原体空肠弯曲杆菌中细菌n -连接糖基化途径。此外,还发现了空肠杆菌及其相关物种大肠弯曲杆菌(campylobacter coli)的氨基糖基化途径。这两种途径都与真核生物中各自的even和do连接的糖基化过程相似。在细菌中,在其他生物中发现了这两种途径中基因的同源物,与糖蛋白相连的复杂聚糖具有共同的生物合成前体,这些修饰可以发挥类似的生物学作用。因此,弯曲杆菌为糖蛋白生物合成的阐明和开发提供了一个独特的模型系统。
Post-translational glycosylation is a universal modification of proteins in eukarya, archaea and bacteria. Two recent publications describe the first confirmed report of a bacterialN-linked glycosylation pathway in the human gastrointestinal pathogenCampylobacter jejuni. In addition, anO-linked glycosylation pathway has been identified and characterized inC. jejuniand the related speciesCampylobacter coli. Both pathways have similarity to the respectiveN- andO-linked glycosylation processes in eukaryotes. In bacteria, homologues of the genes in both pathways are found in other organisms, the complex glycans linked to the glycoproteins share common biosynthetic precursors and these modifications could play similar biological roles. Thus,Campylobacterprovides a unique model system for the elucidation and exploitation of glycoprotein biosynthesis.
