Proton transport into proteoliposomes containing the purified I. tartaricus ATPase and inhibition of H+ transport by Na+ (A) or Li+ (B) ions. Proton transport into the proteoliposomes was determined by the ACMA fluorescence quenching technique. Quenching was elicited by ATP addition; the signal was completely reversed with the uncoupler carbonyl cyanide m-chlorophenylhydrazone (CCCP).
