AccessionGenProp0963
NameO2(Ec) antigen biosynthesis
TypeMETAPATH
DescriptionThe O2 antigen is a branched pentasaccharide observed in strains 1.2741 and 9.1649. It consists of the repeating unit [->3)a-L-Rha-((2<-1)-a-D-Fuc3NAc)-(1->2)-a-L-Rha-(1->3)-b-L-Rha-(1->4)-b-D-GlcNAc-(1->]. Genes for the biosynthesis of Rhamnose and 3-acylamino-fucose (Fuc3NAc), both of which arise from the same intermediate, 4,6-dideoxy-4-oxo-dTDP-D-glucose, are found within the cluster.
