no activity is detected in presence of either 5 mM NADH or 0.5 mM NADPH. Methyl viologen at 20 mM and 0.004 mM ferredoxin I are also tested under the same conditions: activity with 0.004 mM ferredoxin I as reducing agent is approximately 3fold higher than that measured with 20 mM methyl viologen. For the other ferrodoxin isoform found in Haloferax mediterranei, ferrodoxin II, the activity is approximately 8fold lower than that for ferredoxin I

additional information
?
-
-
levels of Fd-GOGAT are coordinated by light, nitrate is necessary for the light regulation. Single or repeated red light pulses induce the activity of the enzymes and this effect is reverted by subsequent far-red light
