FIG. 5.

Representative 2-D gel of BCG cultures grown shaking in low oxygen (1.3% O₂, 5% CO₂) after a 4-day incubation with either 10 mM dbcAMP (A) or 5 mM butyrate (B). Circled protein spots indicate proteins upregulated upon addition of exogenous dbcAMP. Boxed spots indicate proteins where regulation is partially affected by the addition of exogenous butyrate, as well as by the addition of exogenous dbcAMP.
