FIG 3 .
EIIAGlc regulation of integral membrane protein partners is AH dependent. (A to F) Medium acidification (A and B) and growth curves (C to F) carried out in minimal medium supplemented with pH indicators and maltose alone (maltose) or supplemented with α-methylglucoside (maltose + α-MG). (G and H) Northern blot assay of the sRNA csrB in LB-cultured, mid-log-phase cells of the indicated genotype. Samples were harvested at the noted times after addition of rifampin to arrest transcript elongation.
