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 + H2O + 4 H+(in) = ADP + phosphate + 5 H+(out)
CHEBI:30616 + CHEBI:15377 + 4 H+ (in)CHEBI:15378= CHEBI:456216 + CHEBI:43474 + 5 H+ (out)CHEBI:15378
