2.7.8.43
physiological function
in Shigella flexneri serotype X and 4a variants called Xv and 4av, respectively, O-antigen modification with phosphoethanolamine (PEtN) is identified, which is encoded by a plasmid-borne gene lpt-O for a PEtN-transferase and confers the monoclonal antibody IV-1(MASF IV-1) determinant to the bacteria. A correlation between the serotype-specific PEtN modification pattern and the lpt-O variation in different serotypes: lpt-ORII in serotype Xv is better tuned for phosphorylation of RhaII and lpt-ORIII in serotypes Yv and 4av for phosphorylation of RhaII
