Table 2. Half-lives of valU and lysT operon transcripts in various strains.

(A) valU
Species	Half-life (min)
	rph-1	rnpA49 rph-1	rne-1 rph-1	rne-1 rnpA49 rph-1
V	1.0 ± 0.4	7.7 ± 1.4	<0.5	>30
VI	<0.5	>30	<0.5	>30
VII	1.1 ± 0.1	>30	<0.5	>30

(B) lysT
Species	Half-life (min)
	*rph-1*	*rne-1 rnpA49 rph-1*	*rnpA49 rneΔ1019 rng-219 rph-1*	*rne-1 rnpA49 Δrnz Δrng rnlA2 rph-1*
I	<0.5	>30	>30	>30

Species designations are as indicated in Figures 1 and 2. Half-lives were determined as described in the ′Materials and Methods’. Data reflect the averages of at least three independent determinations.
