Abstract The pumps discussed in this review are three members of the phosphorylating class of ion transport ATPases. They are the Na(+)-K(+)-, Ca(2+)- and H(+)-K(+)-ATPases. Recent work on their topology, possible transport mechanisms, ion-binding sites and role of the different subunits found for the Na(+)-K(+)- and H(+)-K(+)-ATPases is presented, with a suggestion of a unifying 10-membrane segment model for the catalytic subunit of this class of enzyme.
