(A) UV–vis spectra of BSA (10 μM, 50 mM Tris-HCl, 50 mM NaCl, pH = 7.2) and complex 1 (0–4.0 μM) reaction. Arrows indicate the direction of change in absorbance. Inset: UV absorption spectra from 240 to 300 nm. (B) Fluorescence spectra of BSA (10 μM, 50 mM Tris-HCl, 50 mM NaCl, pH = 7.2) reacted with complex 1 (0–4.0 μM) (BSA: 10 μM; λex = 280 nm; λem = 343 nm).
