Gene	Operator	Positiona	Kd (nM)	ΔG (kJ/mol)
recA	5′-CGAATATGCGTTCG-3′	−73 (−44)	4.6	−47.6
uvrB	5′-CGAACTTTAGTTCG-3′	−79 (−42)	4.1	−47.9
dinB	5′-AGAACTCATGTTCG-3′	−42 (−14)	3.6	−48.2
dinC (1)	5′-AGAACAAGTGTTCT-3′	−85 (−44)	2.3	−49.3
dinC (2)	5′-CGAACGTATGTTTG-3′	−55 (−14)

^aLocation of 3′ end relative to the ATG codon of the respective gene and (relative to 3′ end of −10 region of canonical promoter sequence).
