FIGURE 6.

Abilities of mutant AcpP plasmids containing Ala or Ile in place of Val-40 and of a plasmid encoding a chimera containing L. lactis AcpA (plus the downstream loop) and AcpP sequences from helix II to the C terminus to support growth of the arabinose-dependent ΔacpP strain in the absence of arabinose. The strains were grown in the presence of IPTG to induce expression of the ACP genes in the presence or absence of Sfp as shown above the plates. The plates were incubated for 24 h at 37 °C.
