Figure 4.
Divergent genetic requirements for substrate export. The graph summarizes the findings presented in Figures 2 and 3. The levels of secreted proteins present in the CF of the Esx-1-deficient strains relative to the WT strain illustrate divergent genetic requirements for substrate export. Brackets with asterisks highlight strains deficient for export of all of the substrates tested, similar to the ΔRD1 strain.
