Biogenesis and function of the yeast plasma-membrane H(+)-ATPase.

Abstract excerpt

One of the most abundant proteins in the yeast plasma membrane is the P-type H(+)-ATPase that pumps protons out of the cell, supplying the driving force for a wide array of H(+)-dependent cotransporters. The ATPase is a 100 kDa polypeptide, anchored in the lipid bilayer by 10 transmembrane alpha-helices. It is structurally and functionally related to the P-type Na(+),K(+)-, H(+),K(+)- and Ca(2+)-ATPases of animal...
