Subunit I is a homolog of subunit A which associates with the membrane-bound complex of eukaryotic vacuolar H+-ATPase (V-ATPase) acidification machinery. The domain forms the proximal lobe that caps one end of the alpha helix bundle, with the distal lobe capping the other end. Although the two lobes exhibit a similar motif, the molecular nature of the coupling with the identical stalks is thought to be dissimilar [1].

Subunit 'a' of V0 (the functional domain responsible for proton transport) sector is highly conserved across eukaryotic species and exists in multiple isoforms. It is the largest subunit of V-ATPases and partitioned almost equally into an N-terminal cytosolic domain and a C-terminal integral membrane. Structure analysis of the N-terminal cytosolic domain from the Meiothermus ruber subunit 'I' homolog of subunit a shows that it is composed of a curved long central alpha-helix bundle capped on both ends by two lobes with similar alpha/beta architecture [1].
