FIG 3 .

Insertion profiles of discrepant genes between data sets. (A) The ftsK gene codes for an essential protein in which only part of the protein is required for its essential function. Such genes have a high insertion index score and consequently would not have been identified by automated statistical analysis. (B) secM contains a window (indicated by an asterisk) of 66 bp in which there were no transposon insertions. This feature is discussed in the text. (C to F) Genes with transposon insertions in only one orientation. The α- and β-orientation of the transposon is depicted above and below the schematic representation of the CDS, respectively, and native promoters are shown in black. (G and H) Many transposon insertions were found along the full length of folK and degS (shown in blue above the schematic map of the figure). However, most of these insertion mutants were lost during outgrowth (below the schematic representation and shown in dark blue).
