Escherichia coli H+-ATPase (ECF1) was inactivated in a time- and concentration-dependent manner by N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ), a selective carboxyl group reagent. Among the subunits of ECF1, only the beta subunit was modified by EEDQ. The reaction of 1 mol of EEDQ per mol of ECF1 resulted in total inactivation, in spite of the fact that the enzyme possesses three beta subunits.
