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. F-type ATPases consist of two structural
CC domains, F(1) - containing the extramembraneous catalytic core, and
CC F(0) - containing the membrane proton channel, linked together by a
CC central stalk and a peripheral stalk. During catalysis, ATP synthesis
CC in the catalytic domain of F(1) is coupled via a rotary mechanism of
CC the central stalk subunits to proton translocation. Part of the complex
CC F(0) domain and the peripheric stalk, which acts as a stator to hold
CC the catalytic alpha(3)beta(3) subcomplex and subunit a/ATP6 static
CC relative to the rotary elements. {ECO:0000256|RuleBase:RU368017}.
CC -!- SUBUNIT: F-type ATPases have 2 components, CF(1) - the catalytic core
CC - and CF(0) - the membrane proton channel. In yeast, the dimeric form
CC of ATP synthase consists of 17 polypeptides: alpha, beta, gamma, delta,
CC epsilon, 4 (B), 5 (OSCP), 6 (A), 8, 9 (C), d, E (Tim11), f, g, h, i/j
CC and k. {ECO:0000256|RuleBase:RU368017}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000256|RuleBase:RU368017}.
CC Mitochondrion inner membrane {ECO:0000256|RuleBase:RU368017}.
CC -!- SIMILARITY: Belongs to the eukaryotic ATPase B chain family.
CC {ECO:0000256|RuleBase:RU368017}.
