glutathione
in the absene of glutathione, only negligible activity is found
NADH
NADH is the preferred electron donor
NADPH
NADH is the preferred electron donor
thioredoxin
the extractable leaf NADPH-dependent MDHAR activity is strongly activated by thioredoxin TRX y2. Activity of recombinant plastid isoform MDHAR6 is more than 2fold increased by reduced TRX y, and not by other plastidial thioredoxins
