Analysis of the salt dependences of non-specific and specific binding of hOGG1.^a

	Slope (N)b	Kanon (M−1)c
KaN	−1.0 ± 0.2	4.0 ± 0.1 × 105
	−1.3 ± 0.3d	8.8 ± 0.6 × 104d
KaTATA	−1.9 ± 0.4	2.6 ± 0.2 × 104
KaGC	−2.0 ± 0.5	2.5 ± 0.3 × 104
KaGCGC	−1.8 ± 0.4	5.4 ± 0.4 ×104
KaS	−2.1 ± 0.3d	1.5 ± 0.1 × 104d

^aAll experiments were conducted using WT hOGG1 unless otherwise noted and the error is derived from the linear fit.

^bThe slope (N) obtained from nonlinear regression fitting to eq 3.

^cK_a^non is the extrapolated value of the K_a to the condition of 1 M [K⁺].

^dThese values were determined using K249Q hOGG1.
