Deletion of lpp protects against lipoprotein maturation and trafficking defects. Relative viability of strains with arabinose-dependent expression of OM lipoprotein biogenesis proteins (Lgt, LspA, Lnt, LolCDE, LolA, or LolB). Viable counts per mL of culture were enumerated in the presence of 0.2% arabinose or in the absence of arabinose and used to determine the fold change in viability when inducer is absent. For LspA strains, the comparison was made between arabinose replete conditions (0.2%) and arabinose deplete (0.002%) conditions. Data represent three independent experiments and the mean.
