FIG. 1.

Coomassie colloidal blue-stained 2-DE gels of supernatant proteins from exponential-phase cultures of NZ131 speB (A) and NZ131 rgg (B). Proteins identified by peptide mass fingerprinting are summarized in Table 3. Diamonds around selected proteins are used to orient the gels to each other. The migration of molecular mass standards is indicated. The gels (oriented with acidic proteins to the left) are representative of two independent experiments.
