B4 cell. Colonies from Pseudomonas sp. B4 polyP-deficient and control cells were grown in LB medium for 48

h. Samples were prepared and analyzed as described in Methods. The upper panels show the separation of proteins in the 5-8 pH range. To have a better resolution of some protein spots a 4.7-5.9 pH range was used (lower panels). Numbers with arrows indicate the spot numbers used for MS/MS analyses (Tables 1 and 2). Figure 5 Summary of protein spots identified whose expression increases during polyP deficiency. A- Planktonic cultures, exponential phase. B- Planktonic cultures, click here stationary phase. C- Colonies grown on LB agar plates. Figure 6 Summary of protein spots identified whose expression decreases during polyP deficiency. A, Planktonic cultures

from exponential phase. PD-1/PD-L1 Inhibitor 3 in vivo B, Planktonic cultures from stationary phase. C, Colonies grown on LB agar plates.
