• 1. Distribution of flavokinase and FAD-pyrophosphorylase in various organs and the cell fractionations were described.2. Flavokinase and FAD-pyrophosphorylase were separated from the same starting tissue by DEAE-Sephadex column chromatography.3. Several properties of the purified enzymes were investigated. The most effective metal ion, optimum pH, activation energy and Michaelis constant were determined.4. Inhibition of flavin enzymes by D-araboflavin showed a competitive one which was distinctly observed on flavokinase and no effect was found on FAD-pyrophosphorylase. This would suggest that the inhibition of araboflavin occurred on the first phosphorylation step of free riboflavin in the body.
