General annotation (Comments)

Function

F1F0 ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F1 containing the extramembraneous catalytic core and F0 containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F1 is coupled via a rotary mechanism of the central stalk subunits to proton translocation By similarity. HAMAP MF_01398

Component of the F0 channel, it forms part of the peripheral stalk, linking F1 to F0 By similarity. HAMAP MF_01398

Subunit structure

F-type ATPases have 2 components, F1 - the catalytic core - and F0 - the membrane proton channel. F1 has five subunits: alpha3, beta3, gamma1, delta1, epsilon1. F0 has four main subunits: a1, b1, b'1 and c(10-14). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. F1 is attached to F0 by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta, b and b' chains By similarity.

Subcellular location

Cellular thylakoid membrane; Single-pass membrane protein By similarity HAMAP MF_01398.

Sequence similarities

Belongs to the ATPase B chain family.
