Furthermore, in most plants, the sensitivity of activase to the ratio of ATP/ADP is modified by the stromal reduction/oxidation (redox) state through another small regulatory protein, thioredoxin.
Hos de fleste planter bliver aktivases følsomhed overfor ATP/ADP-forholdet desuden ændret af stromas reduktion/oxidering (redox)-tilstand via et andet, lille reguleringsprotein, thioredoxin.
