Function
function
Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit.
Catalytic activity
- ATP + 4 H+(in) + H2O = ADP + 5 H+(out) + phosphate
CHEBI:30616 + 4 H+ (in)CHEBI:15378+ CHEBI:15377 = CHEBI:456216 + 5 H+ (out)CHEBI:15378+ CHEBI:43474
