[GOC:ai] EOG8GMXFM GO:0033180 1/2 proton-transporting V-type ATPase, V1 domain cellular_component "A protein complex that forms part of a proton-transporting V-type ATPase and catalyzes ATP hydrolysis. The V1 complex consists of: (1) a globular headpiece with three alternating copies of subunits A and B that form a ring, (2) a central rotational stalk composed of single copies of subunits D and F, and (3) a peripheral stalk made of subunits C, E, G and H. Subunits A and B mediate the hydrolysis of ATP at three reaction sites associated with subunit A." [GOC:mah, ISBN:0716743663, PMID:16449553]
