CC -!- FUNCTION: Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or
CC Complex V) produces ATP from ADP in the presence of a proton gradient
CC across the membrane which is generated by electron transport complexes
CC of the respiratory chain (PubMed:25759169). F-type ATP synthases
CC consist of two structural domains, F(1) - containing the
CC extramembraneous catalytic core, and F(0) - containing the membrane
CC proton channel, linked together by a central stalk and a peripheral
CC stalk (PubMed:27791192). During catalysis, ATP synthesis in the
CC catalytic domain of F(1) is coupled via a rotary mechanism of the
CC central stalk subunits to proton translocation (By similarity). Part of
CC the complex F(0) domain and the peripheral stalk, which acts as a
CC stator to hold the catalytic alpha/ATP1(3)beta/ATP2(3) subcomplex and
CC subunit a/ATP6 static relative to the rotary elements
CC (PubMed:27791192). {ECO:0000250|UniProtKB:Q6C105,
CC ECO:0000269|PubMed:25759169, ECO:0000269|PubMed:27791192}.
CC -!- SUBUNIT: F-type ATP synthases have 2 components, the catalytic core
CC F(1) and the membrane-embedded component F(0), linked together by a
CC central stalk and a peripheral stalk (PubMed:27791192). The central
CC stalk, also called rotor shaft, is often seen as part of F(1)
CC (PubMed:27791192). The peripheral stalk is seen as part of F(0). F(0)
CC contains the membrane channel next to the rotor (PubMed:27791192). F-
CC type ATP synthases form dimers but each monomer functions independently
CC in ATP generation (By similarity). The dimer consists of 18 different
CC polypeptides: ATP1 (subunit alpha, part of F(1), 3 molecules per
CC monomer), ATP2 (subunit beta, part of F(1), 3 molecules per monomer),
CC ATP3 (subunit gamma, part of the central stalk), ATP4 (subunit b, part
CC of the peripheral stalk), ATP5/OSCP (subunit 5/OSCP, part of the
CC peripheral stalk), ATP6 (subunit a, part of the peripheral stalk), ATP7
CC (subunit d, part of the peripheral stalk), ATP8 (subunit 8, part of the
CC peripheral stalk), OLI1 (subunit c, part of the rotor, 10 molecules per
CC monomer), ATP14 (subunit h, part of the peripheral stalk), ATP15
CC (subunit epsilon, part of the central stalk), ATP16 (subunit delta,
CC part of the central stalk), ATP17 (subunit f, part of the peripheral
CC stalk), ATP18 (subunit i/j, part of the peripheral stalk)
CC (PubMed:27791192, PubMed:25759169). Dimer-specific subunits are ATP19
CC (subunit k, at interface between monomers), ATP20 (subunit g, at
CC interface between monomers), TIM11 (subunit e, at interface between
CC monomers) (By similarity). Also contains subunit L (PubMed:25759169).

CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000305|PubMed:27791192}; Multi-pass membrane protein
CC {ECO:0000305|PubMed:27791192}. Note=The F-type ATP synthase complex is
CC anchored in the mitochondrial inner membrane via the F(0) domain with
CC the F(1) domain and the peripheral stalk extending into the
CC mitochondrial matrix. {ECO:0000305|PubMed:27791192}.
CC -!- MASS SPECTROMETRY: Mass=22267; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:25759169};
CC -!- SIMILARITY: Belongs to the eukaryotic ATPase B chain family.
