Alternate gene names: arpB, b1720/b1721; ecfD, b2595; envC, yibP; rluD, sfhB; yfgL, b2512; yfgM, b2513; yncD; b1451; yddW, b1491.
Level expressed in nanograms per OD unit per milliliter after 2 h of growth (post-log phase). The value shown for JH39 represents the average for 15 independent experiments, and the standard deviation was ±22.5. All other values shown are the average for two independent experiments. The values from the data in Fig. 2 are not included in these averages.
A line indicates the levels of expression that are equivalent to the wild-type level plus 1 standard deviation.
Amount of RecA protein relative to that of the wild type (JH39).
This insertion mutant has two transposons (see text).
The transposon insertion in this strain is located between the two genes.
A recA control strain (see legend to Fig. 2 for information on this strain).
