General Information
Term O antigen biosynthetic process ID (Ontology) GO:0009243 (Gene Ontology)
Definition The chemical reactions and pathways resulting in the formation of the O side chain of a lipopolysaccharide, which determines the antigenic specificity of the organism. It is made up of about 50 repeating units of a branched tetrasaccharide.[ ISBN:0198506732 ]
Also Known As "O antigen anabolism" ; "O antigen biosynthesis" ; "O antigen formation" (for all, see Synonyms field below)
