CC -!- FUNCTION: A peripheral cell membrane enzyme that catalyzes the
CC oxidative decarboxylation of pyruvate to form acetate and CO(2). It
CC channels electrons from the cytoplasm to the respiratory chain at the
CC cell membrane via ubiquinone. {ECO:0000256|HAMAP-Rule:MF_00850}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ubiquinone + H2O + pyruvate = a ubiquinol + acetate + CO2;

CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00850};
CC Note=Binds 1 FAD per subunit. {ECO:0000256|HAMAP-Rule:MF_00850};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00850};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00850};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00850};
CC Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00850};
CC -!- ACTIVITY REGULATION: The C-terminus inhibits activity; it has to move
CC for the enzyme to be active. Activated by lipid-binding, which occurs
CC via the C-terminus. {ECO:0000256|HAMAP-Rule:MF_00850}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_00850}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00850};
CC Peripheral membrane protein {ECO:0000256|HAMAP-Rule:MF_00850};
CC Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_00850}.
CC -!- DOMAIN: Has 4 domains; the Pyr domain which binds the pyrimidine moiety
CC of the thiamine pyrophosphate cofactor, the FAD-binding domain, the PP-
CC binding domain which binds the pyrophosphate portion of thiamine
CC pyrophosphate and the C-terminal membrane binding region. The C-
CC terminus is held closely against the rest of the protein and covers the
CC active site; during activation it unfolds from the rest of the protein
CC and forms an amphipathic helix upon membrane binding, exposing the
CC active site. {ECO:0000256|HAMAP-Rule:MF_00850}.
CC -!- SIMILARITY: Belongs to the TPP enzyme family.
CC {ECO:0000256|ARBA:ARBA00007812, ECO:0000256|HAMAP-Rule:MF_00850,
CC ECO:0000256|RuleBase:RU362132}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00850}.
