ADK activity and adenosine and ATP contents in X. campestris pv. campestris strains

Strain^a	ADK activity (pmol AMP min⁻¹ mg protein⁻¹)^b	Adenosine content (nmol g⁻¹ [dry wt] cells)^b	ATP content (μmol g⁻¹ [dry wt] cells)^b at:
Strain^a	ADK activity (pmol AMP min⁻¹ mg protein⁻¹)^b	Adenosine content (nmol g⁻¹ [dry wt] cells)^b	12 h	24 h	36 h
8004 (wild type)	59.1 ± 2.2 a	14.3 ± 2.1 a	3.4 ± 0.18 a	2.52 ± 0.12 a	1.75 ± 0.14 a
0690pk (adk_Xcc mutant)	5.5 ± 0.8 b	142 ± 17 b	2.82 ± 0.13 c	2.01 ± 0.15 c	1.35 ± 0.11 c
C0690pk (complemented mutant)	77 ± 3.8 a	12.6 ± 3.2 a	3.36 ± 0.15 a	2.45 ± 0.18 a	1.83 ± 0.15 a

Strains were cultured in the nutrient-rich complex medium NYG.

Data presented are the means ± standard deviations of triplicate measurements from a representative experiment, and similar results were obtained in two other independent experiments. Different letters a and b indicate significant differences at a P value of 0.01 (t test); a and c indicate significant differences at a P value of 0.05.
