A minimal portion of the glycan (at least two sugars) is required to facilitate flagellar assembly and the presence of each additional sugar results in increased motility, as measured on semi-swarm plates. Glycan Information Glycan Annotation Linkage: β-GalNAc-Asn. N-linked tetrasaccharide (1036.4 Da) composed of N-acetylgalactosamine, di-acetylated glucuronic acid, an acetylated and acetamidino-modified mannuronic acid linked to threonine, and a novel terminal sugar: Sug-4-β-ManNAc3NAmA6Thr-4-β-GlcNAc3NAcA-3-β-GalNAc-Asn where Sug is a novel monosaccharide unit, (5S)-2-acetamido-2,4-dideoxy-5-O-methyl-α-L-erythro-hexos-5-ulo-1,5-pyranose.
