Abstract


The N-terminus of V-ATPase subunit E has been shown to associate with the subunits C, G and H, respectively. To understand the assembly of E with its neighboring subunits as well as its N-terminal structure, the N-terminal region, E(1-69), of the Saccharomyces cerevisiae V-ATPase subunit E was expressed and purified. The solution structure of E(1-69) was determined by NMR spectroscopy. The protein is 90.3 Å in length and forms an á-helix between the residues 12-68. The molecule is amphipathic with hydrophobic residues at the N-terminus, predicted to interact with subunit C. The polar epitopes of E(1-69) are discussed as areas interacting with subunits G and H.
