NameO91(Ec) antigen biosynthesis
TypeMETAPATH
DescriptionThe O91 antigen in E. coli is a linear pentasaccharide with the structure: [-->4)-a-D-Qui3NAcyl-(1-->4)-b-D-Gal-(1-->4)-b-D-GlcNAc-(1-->4)-b-D-GlcA6NGly-(1-->3)-b-D-GlcNAc-(1-->], where Acyl=(R)-3-hydroxybutyryl (Note that this is the structure as reported in the ECODAB database, whereas the original publication [1] has this permuted such that the b-D-galactose sugar is in the first position).
