e., Pkon) being (1.9 ± 0.2) × 104 M-1 s-1. However, in the presence of ·NO, Mb(III)-mediated detoxification of peroxynitrite is only partially inhibited, underlying the possibility that also Mb(III)-NO is able to catalyze the peroxynitrite isomerization, though with a reduced rate (Pkon* = (2.8 ± 0.3) × 103 M-1 s-1). These data expand the multiple roles of ·NO in modulating heme-protein actions, envisaging a delicate balancing between peroxynitrite and ·NO, which is modulated through the relative amount of Mb(III) and Mb(III)-
