Evidence that there are two copies of subunit c" in V0 complexes in the vacuolar H+-ATPase.

The Biochemical journal - 15 Sept 2002

Gibson Lucien C D, Cadwallader Graham, Finbow Malcolm E

Abstract excerpt

The proton-translocating core of eukaryotic vacuolar H(+)-ATPase (V-ATPase), V(0) consists of a hexameric arrangement of transmembrane alpha-helices formed from the related polypeptides, subunit c and subunit c". The former is comprised of four transmembrane alpha-helices, whilst the latter has an extra transmembrane domain at its N-terminus. In addition, the fungal form of V(0) contains a minor subunit c-related...
