A. Scheme of the reaction of cPTIO with •NO producing cPTI and •NO2. B. The EPR spectra of 0.5 mM solutions of cPTIO (•; aN1=aN3=8.1 G) and cPTI (o; aN1=9.8 G, aN3=4.6 G). The solution of cPTI was obtained upon titration of cPTIO solution with •NO donor, Proli NONOate, as described in Materials and Methods. C. The reaction of cPTIO with Angeli’s salt: the kinetics of cPTIO decay (filled symbols) and cPTI formation (empty symbols) were measured by EPR in solution of 0.5 mM cPTIO after addition of 0.16 mM AS alone (o) or 0.16 mM AS and 0.5 mM hydroxylamine, hcPTI (□).
