O2-binding to fully reduced cytochrome aa3 reexamined using SVD analysis of simulated and real data.
Using new time-resolved multichannel experimental and simulated data, analyzed by SVD, it is concluded that the second order binding rate constant for O2-binding to fully reduced mammalian cytochrome aa3 is approximately five times higher than the currently accepted value of approximately 1.5 x 10(8) M-1 s-1.
