FIGURE 8.

The effects of NanR and NagC and their respective inducers Neu₅Ac and GlcNAc on the β-galactosidase produced by a FimB-LacZ fusion in the presence and absence of SlyA. Strains BGEC905 (wild type), KCEC357 (ΔnanR), and KCEC505 (ΔnagC) (dark bars) and ΔslyA mutant derivatives (light bars) of these strains KCEC1334, KCEC1275, and KCEC1278, respectively, were used. Error bars and experimental conditions are described in Fig. 2. 3 mm Neu₅Ac or GlcNAc were included in the medium as indicated.
