Alternate gene names: arpB, b1720/b1721; ecfD, b2595; envC, yibP; rluD, sfhB; yfgL, b2512; yfgM, b2513; yncD, b1451; yddW, b1491.

b

A line indicates the levels of expression that are equivalent to the wild-type level plus 1 standard deviation.

c

Number of β-galactosidase units expressed after 2 h of growth (post-log phase). The values shown are the average of results for at least three independent experiments. Standard deviations are shown in parentheses.

d

Relative units of β-galactosidase compared to that of the wild type (JH39).

e

This insertion mutant has two transposons (see text).

f

The transposon insertion in this strain is located between the two genes.

g

A recA control strain (see legend to Fig. 2 for information on this strain).
