title: The proton-translocating ATPase of Candida tropicalis plasma membrane.
abstract: Proton translocation activity of Candida tropicalis plasma membrane ATPase has been demonstrated using a fluorescent delta pH probe (ACMA) and by direct pH measurements. Modifications in fluorescence intensity and H+ transport are highly specific for Mg2+ and ATP, and are sensitive to the well-known inhibitors of the plasma membrane ATPase, vanadate and DCCD. A H+/ATP ratio of 0.54 is found.
