Previous preparations of the Na + F1F0-ATP synthase solubilized by Triton X-100 lacked some of the membrane-embedded motor subunits [Reidlinger J&Mu¨ller V (1994) Eur J Biochem233, 275–283]. To improve the subunit recovery, we revised our purification protocol. The ATP synthase was solu-bilized with dodecylmaltoside and further purified to apparent homogeneity by chromatographic techniques.

The Vps4 C-terminal helix is a critical determinant for assembly and ATPase activity and has elements conserved in other members of the meiotic clade of AAA ATPasesSorting of membrane proteins into intralumenal endosomal vesicles, mul-tivesicular body (MVB) sorting, is critical for receptor down regulation, antigen presentation and enveloped virus budding. Vps4 is an AAA ATPase that functions in MVB sorting. Although AAA ATPases are oligo-meric, mechanisms that govern Vps4 oligomerization and activity remain elusive. Parimala R. Vajjhala1,2, Chau H. Nguyen1,2, Michael J.
