Figure 5: PhoR regulates olsB gene expression and aminolipid formation in A. baumannii strains.

Figure 5:

A. Predicted Pho box sequence alignments from A. baumannii strain 17978, 19606, AB5075, AYE, and A. baylyi olsB promoters. Black asterisks represent conserved nucleotides in the E. coli Pho box consensus (CTGTCATNNNNCTGTCAT). B. 2D thin-layer chromatography lipid analysis from A. baumannii strain ATCC 17978 wild type and mutants grown in minimal media supplemented with 50 μM (limiting) phosphate. C. 2D thin-layer chromatography lipid analysis from A. baumannii strain AB5075 wild type and the phoR Tn26 mutant in minimal media supplemented with 50 μM (limiting) phosphate. Lipids were stained with sulfuric acid. OL and LL aminolipids are labelled in red.
