Abstract excerpt
The plasma membrane proton pump (H(+)-ATPase) found in plants and fungi is a P-type ATPase with a polypeptide sequence, structure, and in vivo function similar to the mammalian sodium pump (Na(+), K(+)-ATPase). Despite its hypothetical importance for generating and maintaining the proton motive force that energizes the carriers and channels that underlie plant nutrition, genetic evidence for such a central...
