Dicyclohexylcarbodiimide (DCCD) specifically inhibits the F1F0-H+-ATP synthase complex of Escherichia coli by covalently modifying a proteolipid subunit that is embedded in the membrane. Multiple copies of the DCCD-reactive protein, also known as subunit c, are found in the F1F0 complex. In order to determine the minimum stoichiometry of reaction, we have treated E. coli membranes with DCCD, at varying concentrations and for varying times, and correlated inhibition of ATPase activity with the… CONTINUE READING
