  • Title: Structure, molecular genetics, and evolution of vacuolar H+-ATPases.
    Author: Nelson N.
    Journal: J Bioenerg Biomembr; 1989 Oct; 21(5):553-71. PubMed ID: 2531737.
    Abstract:
    Proton-ATPases can be divided into three classes denoted as P-, F-, and V-ATPases. The P-ATPases are evolutionarily distinct from the F- and V-type ATPases which have been shown to be related, probably evolved from a common ancestral enzyme. Like F-ATPases, V-ATPases are composed of two distinct structures: a catalytic sector that is hydrophilic in nature and a hydrophobic membrane sector which functions in proton conduction. Recent studies on the molecular biology of vacuolar H+-ATPases revealed surprising findings about the evolution of pronon pumps as well as important clues for the evolution of eukaryotic cells.
