Figure 5.
Peptide oxidation catalyzed by the a and a’ domain of Erp41.A, example of fluorescence profile (F.U., fluorescence units) in a peptide oxidation reaction, catalyzed by the a’ domain in the presence of 0.5 mM GSSG. Residual of the fit to a single exponential function is shown above the trace. B and C, GSSG titration of the rate of oxidation catalyzed by the a domain (B) and a’ domain (C). n = 3 to 5, data represented as average and SD.
