Comments [?]

Function Produces ATP from ADP in the presence of a proton gradient across the membrane.
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, b and c.
case <OG:Chloroplast>
Subcellular location Plastid, chloroplast thylakoid membrane; Peripheral membrane protein.
else case <OC:Cyanobacteria> and not <OC:Gloeobacter>
Subcellular location Cellular thylakoid membrane; Peripheral membrane protein.
else case <OC:Gloeobacter>
Subcellular location Cell inner membrane; Peripheral membrane protein.
else case not defined <Property:Membrane> or <Property:Membrane=1>

Comments Divergent CAUVC and CHLLI not shown in alignment. ACEWO and PROMO are sodium-specific; it is not possible to distinguish proton-depedent ATPase subunits from sodium-dependent ones. FRACC and NOVAD are 87 residues long and marked as atypical.
