Both eukaryotic and prokaryotic cells depend strongly on the
function of ion pumps present in their membranes. The term ion
pump, synonymous with active ion-transport system, refers to a
membrane-associated protein that translocates ions uphill against
an electrochemical potential gradient. Primary ion pumps utilize
energy derived from chemical reactions or from the absorption of
light, while secondary ion pumps derive the energy for uphill
movement of one ionic species from the downhill movement of another
species.
In the present volume, various aspects of ion pump structure,
mechanism, and regulation are treated using mostly the
ion-transporting ATPases as examples. One chapter has been devoted
to a secondary ion pump, the Na+-Ca2+ exchanger, not only because
of the vital role played by this transport system in regulation of
cardiac contractility, but also because it exemplifies the
interesting mechanistic and structural similarities between primary
and secondary pumps.
