General annotation (Comments)

Function

Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. HAMAP MF_01346

Catalytic activity

ATP + H2O + H+(In) = ADP + phosphate + H+(Out). HAMAP MF_01346

Subunit structure

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 three main subunits: a1, b2 and c(9-12). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. CF1 is attached to CF0 by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta and b chains By similarity.

Subcellular location

Cell membrane; Peripheral membrane protein By similarity HAMAP MF_01346.

Sequence similarities

Belongs to the ATPase alpha/beta chains family.
