PolysacDB ID2564
Carbohydrate NameO-polysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeXanthomonas hyacinthi S148   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe Xanthomonas LPS showed a predominance of mannose (Man), glucose (Glc), galacturonic acid (GalA), and N-acetylglucosamine (GlcNAc) residues
BCSDB StructureN/A
Proposed functionsN/A
Antigenic Nature used to produce antibodiesCrude cell wall preparation and purified fimbriae
Carrier NameNil
Conjugation MethodNil
AntibodiesMab 2E5
Antibody type and classIgM
Assay SystemImmunoblotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA), and immunoelectron microscopy
Cross-reactivityThis Mab cross-reacted with all X. hyacinthi strains. No cross-reaction was found with 27 other Xanthomonas pathovars tested or with 14 other bacterial species from other genera, such as Erwinia and Pseudomonas
Proposed epitopesThe O antigen was found to consist of rhamnose and fucose in a 2:1 molar ratio. Mab 2E5 recognized only S-LPS and did not recognize R-LPS
IEDB EpitopeN/A
Proposed UtilityThis Mab could be useful for structural studies, for detection purposes in commercial and agricultural settings, and for serological typing purposes
