A. W estern blot of the soluble and insoluble fractions of the CCCP-treated E. coli MPh42 cells. Cells were initially grown up to [OD]600 nm ≈ 0.5 at 30°C in complete MOPS medium and were subsequently transferred to phosphate-less MOPS medium. They were then further allowed to grow at 30°C in the presence of 50 μM CCCP. At different instants of growth, the soluble and insoluble cell fractions were isolated as described in 'Methods' section. Lanes a, b, c represent the soluble and lanes e, f, g represent the insoluble fractions, isolated at 30, 60 and 90 min of growth respectively. Lane d represents purified AP. B. Degradation of AP-aggregates in CCCP-treated cells, after removal of CCCP. Lanes (a, b), (c, d) and (e, f) represent 0 hr and 3 hr of chasing for the strains SG20250, SG22159 and JT4000 respectively.
