LITERATURE

ATP
the enzyme reaches its maximal activity at an ATP concentration of about 1.4 mM. The enzyme activity decreases by 20% when the concentration of ATP is higher than the physiologically relevant concentration (about 5 mM)
CTP
the activity of the enzyme reaches its maximal activity at a CTP concentration of about 1.4 mM. The maximal activity decreases by 68 and 95% when the concentration of CTP is 5.7 and 11.4 mM, respectively
Dithionite
-
presence of sodium dithionite is required for the transformation of FMN into FAD
dithiothreitol
-
FMNAT activity is very poor in the presence of milder reducing agents such as DTT
reduced glutathione
-
stimulates FAD hydrolysis
