Structural characterization and biosynthesis of quinovosan, a deoxyhexose homopolymer involved in crust architecture of Bacillus subtilis spores

Elodie Evangélaire, Christelle Lemy, Nao Yamakawa, Frédéric Krzewinski et autres

Bacillus subtilis spores persist on food-processing equipment surfaces, contributing to the contamination of finished products and food loss. Their outermost layer, the crust, influences spore adhesion, notably through its glycans, whose structures remain unknown. Here, we report the identification and structural characterization …

Uncommon N-Glycan Structures in Anhydrobiotic Tardigrades

Hirokazu Yagi, Taiki Saito, Shih-Yun Guu, Nao Yamakawa et autres

We characterized the N-glycosylation profiles of anhydrobiotic tardigrades, Ramazzottius varieornatus and Hypsibius exemplaris, identifying high-mannose, paucimannose, and complex-type oligosaccharides, while hybrid-type glycans were undetectable. Notably, paucimannose-type oligosaccharides accounted for 39% of the N-glycans in R. varieornatus and 17% in H. exemplaris, with …

Sialylated glycoproteins and sialyltransferases involved in mesoderm-derived organ formation during embryogenesis

Ingrid Fliniaux, Pélagie Douchez, Yoshiko Takeda-Uchimura, Marin Matthieu et autres

Most major organs, like muscles, bones, vessels and kidneys, develop from the mesoderm, one of three germ cell layers in triploblastic organisms. Sialic acids significantly affect embryonic development by regulating cell division, migration and death through signaling pathways and cell adhesion, which …
