0.1 mM, 71% inhibition
-
after 2 h at 2 mM, complete inactivation by dinitrophenylation of 2 mol of histidine residues per mol of enzyme-bound FMN, competitive inhibitors such as phosphate, nitrate and alpha-hydroxymalonate decrease the rate of inactivation
-
i.e. Sanger's reagent
-
11% residual activity at 2.5 mM
-
reversible
-
irreversible, with NADPH, alkylation of the active site cysteine disulfide, strong increase in oxidation activity of the enzyme against NADPH
-
1 mM, 2% activity
-
up to 90% inhibition at pH 6.5-7.0, slight increase at pH 9.0 when Mg2+ is the metal cofactor. 3fold increase of activity at alkaline pH, less activation at neutral pH when Mn2+ is the metal cofactor
