Figure 4.
Stopped-flow UV/Vis measurements of (A) MnII-FeBMb(FeII) and (B) CoII-FeBMb(FeII) upon reaction with O2-saturated 100mM potassium phosphate pH 6 buffer between 1ms and 300s. The coloring order of each trace (from earliest to latest) is black (1ms) → green (for MnII-FeBMb(FeII), 20ms) → blue (600ms) → red (300s).
