Method (P.175 right column top paragraph:) "The maturation kinetics was slow enough to monitor in real time with a spectrofluorometer and fitted well to a single exponential curve, suggesting that the oxidation step is the rate-limiting step in the overall chromophore maturation process (Figs. 1 and 2 see also supplementary material). The observed rate constant was defined as the rate constant of de novo chromophore maturation."
Comments "During earlier years, the maturation rate of GFP was determined as the rate of fluorescence development after admission of air to anaerobically expressed GFP [ref 5]. Currently, conventional methods to study the maturation kinetics are based on triggering protein folding of urea-solubilized inclusion bodies [ref 9] and reoxidation of the chromophore after chemical reduction of the mature chromophore [refs 9–13]. However, inconsistent data have been reported (Table 1)."
