Figure 6From: The binding characteristics of isoniazid with copper–zinc superoxide dismutase and its effect on enzymatic activityThree-dimensional fluorescence spectra of SOD (A) and the INH–SOD system (B) (pH = 7.4, T = 299 K). A c (SOD) = 4.0 × 10−6 mol · L−1, c (INH) = 0; B c (SOD) = 4.0 × 10−6 mol · L−1, c (INH) = 4.0 × 10−5 mol · L−1.Back to article page
