FIG 4.

E. coli C122 upregulates membrane-stabilizing and -anchoring proteins Lpp, OmpA, and Pal during φX174 infection. Upregulation of the membrane lipoprotein maturation and transportation pathway. Depicted are nascent lipoproteins translocating across the inner membrane through the Sec pathway, followed by processing, and Lol pathway-mediated export to the outer membrane. Outer membrane proteins are depicted, including OmpA, which has its peptidoglycan-anchoring role highlighted along with Lpp and Pal. Values indicate protein fold change during infection (75P/75C protein samples), n.o, protein not observed; n.s, protein observed but not significantly altered in abundance between conditions.
