FIG. 4.
Regulation of high-molecular-mass secreted proteins by Ler. (A) Coomassie blue-stained gels of secreted protein preparations from EPEC and EHEC demonstrated that ∼110-kDa proteins were not secreted from Δler mutants. (B) Antibodies identify this protein in EPEC supernatants as EspC. wt, wild type.
