Effects of reduction and oxidation of the 46-kDa isoform via thioredoxin-f. The 46-kDa isoform was either untreated (■), reduced with DTT and thioredoxin-f (●), or reduced with DTT and thioredoxin-f and then oxidized with glutathione (GSSG) (▵), as described in the text. The ATPase activity at the indicated ADP/ATP ratios (A) or the ability of the protein to activate Rubisco at an ADP/ATP ratio of 0.33 (B) was then determined. In B, activation of Rubisco with time in the absence of activase (▿) is also shown.
