CC -!- FUNCTION: Mitochondrial membrane ATP synthase (F(1)F(o) ATP synthase)
CC produces ATP from ADP in the presence of a proton gradient across the
CC membrane which is generated by electron transport complexes of the
CC respiratory chain (PubMed:19436713, PubMed:29247468). F-type ATPases
CC consist of two structural domains, F(1) - containing the
CC extramembraneous catalytic core, and F(o) - containing the membrane
CC proton channel, linked together by a central stalk and a peripheral
CC stalk (PubMed:19436713, PubMed:29247468, PubMed:29440423). During
CC catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via
CC a rotary mechanism of the central stalk subunits to proton
CC translocation. Subunits alpha and beta form the catalytic core in F(1)
CC (PubMed:19436713, PubMed:29440423). Rotation of the central stalk
CC against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of
CC ATP in three separate catalytic sites on the beta subunits (Probable).
CC Contrary to the procyclic, insect form that requires F(1)F(o) ATP
CC synthase for ATP synthesis, the bloodstream form relies on ATP
CC hydrolysis by F(1)F(o) ATP synthase to maintain its mitochondrial
CC membrane potential (PubMed:29247468). {ECO:0000269|PubMed:19436713,
CC ECO:0000269|PubMed:29247468, ECO:0000269|PubMed:29440423, ECO:0000305}.
CC -!- SUBUNIT: F-type ATPases have 2 components, F(1) - the catalytic core
CC - and F(o) - the membrane proton channel. F(1) has five subunits:
CC alpha(3), beta(3), gamma(1), delta(1), epsilon(1), plus the additional
CC subunit P18 (Tb427.05.1710) that is not present in F(1)F(o) ATP
CC synthase from metazoa (PubMed:19436713, PubMed:29247468,
CC PubMed:29440423). Subunit P18 (Tb927.5.1710) interacts with the alpha
CC subunit with a 1:1 stoichiometry; the interaction is direct
CC (PubMed:29440423). Subunit gamma is part of the central stalk
CC (PubMed:29440423). F(o) has three main subunits: a, b and c
CC (PubMed:19436713). The trypanosomal ATPase complex contains additional
CC subunits that are not present in the F(1)F(o) ATP synthase from metazoa
CC (PubMed:19436713, PubMed:29247468, PubMed:29440423).
