Popis: The C epitope of Brucella O-polysaccharide (O-PS) has so far lacked definitive structural identity. Revised structures for this antigen revealed a unique capping perosamine tetrasaccharide consisting of a sequence of 1,2:1,3:1,2 interresidue linkages. Here, using synthetic oligosaccharide glycoconjugates, the α-1,3 linkage of the O-PS is shown to be an integral structural requirement of this epitope. Although A-dominant strains possess only one or two copies of the capping tetrasaccharide, this creates a unique pentasaccharide antigenic determinant with the linkage sequence 1,2:1,3:1,2:1,2 that is always present in major pathogenic Brucella species.
