Correction of GFP concentration and synthesis rate for folding time. (a) Concentration profile of active GFP (blue line) and total GFP (green line). The latter profile has been corrected for the folding time of GFP. Both profiles are normalized with respect to the peak in mid-exponential phase of the active GFP concentration. (b) Concentration profile of gfp mRNA, before correction (blue line) and after correction (green line) for the folding time. Normalization is as in panel a.
