Function
function
Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits.
Catalytic activity
- ATP + H2O + 4 H+(in) = ADP + phosphate + 5 H+(out)

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: a1, b1, b'1 and c(9-12).
