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

Interaction
Subunit
F-type ATPases have 2 components, CF1 - the catalytic core - and CF0 - the membrane proton channel. CF1 has five subunits: alpha3, beta3, gamma1, delta1, epsilon1. CF0 has four main subunits: a, b, b' and c.
