Figure 5. Comparison of the Protein Secretion Capabilities of the Parent and ΔerpΔpδ Strains.
Panel a, comparison of extracellular protein concentrations and enzymatic activities between the parent and ΔerpΔpδ strains. Closed square, parent strain; open square, ΔerpΔpδ strain. Panel b, comparison of intracellular protein concentrations and specific enzymatic activities between the parent and ΔerpΔpδ strains. Closed square, parent strain; open square, ΔerpΔpδ strain. Error bars indicate the standard deviation calculated from three biological experiments.
