WebN -Glc is a prokaryote-specific modification that is found in selected Gram-negative bacteria, where it is most commonly found on cell-surface proteins such as (autotransporter) adhesins, biosynthesized as part of the three-protein HMW cluster including the N -glucosyl transferase HMW1C. WebA sequon is a sequence of consecutive amino acids in a protein that can serve as the attachment site to a polysaccharide, frequently an N-linked-Glycan. [1] The polysaccharide is linked to the protein via the nitrogen atom in the side chain of asparagine (Asn).
