Carbohydrate NameO-polysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeActinobacillus pleuropneumoniae serotype 1 shope 4074   (NCBI Taxonomy)   (Drugpedia)
Basic StructureThe O-polsaccharide structure is as follows :
--6)-α-D-Glcp-(1-->2)-α-L-Rhap-(l-->2)-α-L-Rhap-(1--. which is linked to 1-D-GlcpNAc chains on its rhamnopyranosyl residue via 1-->3 linkage.
BCSDB StructureN/A
Proposed functionsLPS is an important virulence factor. It molecule plays an important role in adherence of the bacterium to porcine respiratory tract cells and mucus
