ChEBI IDCHEBI:137206
ChEBI NameBrucella O-antigen
Stars
ASCII NameBrucella O-antigen
DefinitionA diblock copolymer in which one block consists of tetrasaccharide components comprising N-formyl-α-D-perosamine residues linked sequentially (1→2), (1→3) and (1→2) [α-D-Rhap4NFo-(1→2)-α-D-Rhap4NFo-(1→3)-α-D-Rhap4NFo-(1→2)-α-D-Rhap4NFo], with the second block consisting of N-formyl-α-D-perosamine residues linked solely (1→2). The percentage of (1→3) linkages compared with (1→2) ranges from 1% to 20% in different Brucella biovars.
