This mechanism uses ferredoxin reduced by the photosynthetic electron transport chain together with two chloroplast proteins (ferredoxin-thioredoxin reductase and thioredoxin) to regulate fructose 1,6-bisphosphatase, sedoheptulose 1,7-bisphosphatase, phosphoribulokinase, and NADP-glyceraldehyde-3-phosphate dehydrogenase (Figure 8.6). (...) The cleavage of the enzyme disulfide bonds causes a conformational change that increases catalytic activity (see Figure 8.6). (...) NADP-malate dehydrogenase is regulated via the ferredoxin-thioredoxin system as in C3 plants (see Figure 8.6).
