ChIP-chip analysis of wild-type (WT) and RpoZ-defective mutant RNAP. The ChIP-chip analysis was performed for E. coli K-12 wild-type BW25113 and its rpoZ-deleted mutant JW3624 under the standard procedure (78, 79). The ratio of the binding level of rpoZ mutant to that of wild type was plotted along the E. coli K-12 genome. The peaks located within open reading frames are shown in orange, while the peaks located inside the spacer are shown in green. The list of genes with high-level distribution of RpoZ-lacking RNAP is given in Table 1, while the locations of these genes along prophages are shown in Fig. 2.
