Comments [?]

FUNCTIONF(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.
FUNCTIONComponent of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0).
case <OG:Chloroplast> or <OC:Cyanobacteriota>
SUBUNITF-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.

Comments MF_01398 signature matches b and b' subunits, but this rule is specific for b subunit annotation. See MF_01399 for b' subunit annotation. This family includes potential copies of the b' subunit in non- cyanobacteria; however all are now called subunit b. Quite a few non-model bacteria have more than 1 copy of this protein, including potential copies of the b' subunit; exactly which copies are found in the enzyme requires more study. In Mycoplasma pneumoniae (ATCC 29342 / M129) this is a lipoprotein; this is suggested for similar Mycoplasmataceae. Sometimes predicted to have 2 transmembrane helices. In some of the Mycobacteria one copy is fused with the delta subunit. Some have a longer C-terminus. For a review on the peripheral (stator) stalk see PubMed=16730323; DOI=10.1016/j.bbabio.2006.04.007; Weber J.; "ATP synthase: subunit-subunit interactions in the stator stalk."; Biochim. Biophys.
