Figure 3.
E. coli with various genetic deletions in the biosynthetic pathway of LPS were tested for their ability to bind fluorescently labeled GP12. Top, specified mutants were incubated for 30 min with fluorescein-tagged GP12 and analyzed using flow cytometry. Data are represented as mean ± SD (n = 3). Bottom, schematic representation of LPS that relates to the mutant shown in the top panel. The red spheres represent phosphorylation sites.
