proton-transporting V-type ATPase, V1 domain
id: GO:0033180
name: proton-transporting V-type ATPase, V1 domain
namespace: cellular_component
type: go
obsolete: False
Description: 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.
