FIGURE 6.
Dose-response curves of NOsGC wild-type enzyme and NOsGC mutants. Concentration-dependent activation of α1S/β1, α1S-W352F,W669A/β1-W22F,W602F and α1S-W466F/β1 was measured in a range of 1 nm to 100 μm DEA/NO or 0.1 nm to 100 μm BAY 41-8543 in the presence of DEA/NO (100 μm). A, fold stimulation by DEA/NO. B, fold stimulation by BAY 41-8543 in the presence of DEA/NO. C and D, same data as in A and B normalized to the maximum. The results are expressed as means ± S.E. of at least three independent experiments.
