Abstrakt: 1,5-Difluoro-2,4-dinitrobenzene completely inhibits F 1-ATPase when it is used at micromolar concentrations and the inhibitor/enzyme molar ratio is equal to 3. The inhibition can be reversed by dithiothreitol treatment. 7-Chloro-4-nitrobenzofurazan treatment of F 1-ATPase does not prevent the reaction of the enzyme with 1,5-difluoro-2,4-dinitrobenzene. The 1,5-difluoro-2,4-dinitrobenzene-induced inhibition is thought to be a result of the modification of a tyrosine residue with p K9.1.
