FIG. 5.

Identification of members of the C. jejuni iron and Fur regulons by 2-D gel electrophoresis. Four different classes of regulation are illustrated, with the number of C. jejuni proteins belonging to each class indicated. From each class, one example from 2-D gels with the surrounding region is included, with the pI decreasing from left to right. The approximate pI of the regulated protein is indicated below the relevant photograph; the estimated molecular mass is shown at the right.
