Impact of Mia40 and GSSG in the oxidative folding reaction of hCox17. (A) Reduced hCox17 was allowed to refold in the presence of Mia40 (molar ratio 1:2) and the reaction analyzed by RP-HPLC. (B) The normalized peak area of reduced (red triangles), intermediate (blue squares) and native (green circles) species are represented as a function of time in the presence (left) and absence (right) of Mia40. The fitting to a U-I-N transition is displayed in solid lines. (C) hCox17 folding intermediate disappearance as a function of time in the presence of Mia40 (open circles) and in stop and go assays (solid squares). A dashed line at 50% is also represented to identify the half-life of the specie. (D) RP-HPLC chromatograms of hCox17 folding reaction in the presence of 1 mM GSSG. Red boxes highlight off-pathway intermediates.
