Plus signs in the column [Gel 1–9] (A) indicate a clear induction in a ςB-dependent manner at the protein level in the wild type compared to the ςB-mutant strain (see also Fig. 3). Minus signs show an overlaying effect of additional regulators masking the ςB dependency. Filled squares at positions 1 to 9 in the column [Gel 1–9] (B–E) point out high synthesis in the corresponding gels (see Figs. 1 and 2). X signs indicate very weak expression levels of the corresponding spots.
