The enterohaemorrhagic Escherichia coli (serotype O157:H7) Tir molecule is not functionally interchangeable for its enteropathogenic E. coli (serotype O127:H6) homologue

Abstract excerpt

A major virulence determinant of enteropathogenic Escherichia coli (EPEC) is the Tir molecule that is translocated into the plasma membrane where it orchestrates cytoskeletal rearrangements. Tir undergoes several phosphorylation events within host cells, with modification on a tyrosine essential for its actin-nucleating function. The EHEC (serotype O157:H7) Tir homologue is not tyrosine phosphorylated implying...
