Comments [?]

Function Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane.
case <OG:Chloroplast> or <Property:PHOTOSYN>
Subunit F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has four main subunits: a, b, b' and c.
else
Subunit F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main subunits: a(1), b(2) and c(9-12). The alpha and beta chains form an alternating ring which encloses part of the gamma chain. CF(1) is attached to CF(0) by a central stalk formed by the gamma and epsilon chains, while a peripheral stalk is formed by the delta and b chains.

case <OG:Chloroplast>
Subcellular location Plastid, chloroplast thylakoid membrane; Multi-pass membrane protein.
else case <OC:Cyanobacteriota> and not <OC:Gloeobacter>
Subcellular location Cellular thylakoid membrane; Multi-pass membrane protein.
else case <OC:Gloeobacter>

else case not defined <Property:Membrane> or <Property:Membrane=1>
Subcellular location Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
Subcellular location Cell inner membrane; Multi-pass membrane protein.
end case
Similarity Belongs to the ATPase A chain family.
