Comments
FUNCTION: F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation (By similarity).
FUNCTION: Key component of the F(0) channel; it plays a direct role in translocation across the membrane. A homomeric c-ring of between 10-14 subunits forms the central stalk rotor element with the F(1) delta and epsilon subunits (By similarity).

case <OG:Chloroplast> or <Property:PHOTOSYN>
SUBUNIT: F-type ATPases have 2 components, F(1) - the catalytic core - and F(0) - the membrane proton channel. F(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). F(0) has four main subunits: a(1), b(1), b'(1) and c(10-14). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. F(1) is attached to F(0) 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).

Comments: For a review see : PubMed=18515057; DOI=10.1016/j.abb.2008.05.004; Nakamoto R.K., Baylis Scanlon J.A., Al-Shawi M.K.; "The rotary mechanism of the ATP synthase."; Arch. Biochem. Biophys. 476:43-50(2008). The number of subunits in this proton turbine determines the H+/ATP ratio and therefore the efficiency of energy conversion (PubMed:18206981). The K subunit of the V-type sodium ATPase of Enterococcus hirae, and probably other organisms, may fall into this family. However they have 2 ATP c synthase domains, whereas the non V-type subunits only have 1. Thus they have not been currently included in this family. STROR has a low score against the profile and has been made atypical.
