CC -!- FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall
CC conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the
CC glycolytic pathway to the tricarboxylic cycle. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-N(6)-lipoyl-L-lysyl-[dihydrolipoyllysine-residue
CC acetyltransferase] + H(+) + pyruvate = (R)-N(6)-(S(8)-
CC acetyldihydrolipoyl)-L-lysyl-[dihydrolipoyllysine-residue
CC acetyltransferase] + CO2; Xref=Rhea:RHEA:19189, Rhea:RHEA-COMP:10480,
CC Rhea:RHEA-COMP:10481, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:83099, ChEBI:CHEBI:83111; EC=1.2.4.1;
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Pyruvate dehydrogenase activity is inhibited by
CC phosphorylation of PDHA1; it is reactivated by dephosphorylation.
CC {ECO:0000250}.
CC -!- SUBUNIT: Heterotetramer of two PDHA1 and two PDHB subunits. The
CC heterotetramer interacts with DLAT, and is part of the multimeric
CC pyruvate dehydrogenase complex that contains multiple copies of
CC pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (DLAT,
CC E2) and lipoamide dehydrogenase (DLD, E3). These subunits are bound to
CC an inner core composed of about 48 DLAT and 12 PDHX molecules (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC -!- PTM: Phosphorylation at Ser-232, Ser-293 and Ser-300 by PDK family
CC kinases inactivates the enzyme; for this phosphorylation at a single
CC site is sufficient. Phosphorylation at Ser-293 interferes with access
CC to active site, and thereby inactivates the enzyme. Dephosphorylation
CC at all three sites, i.e. at Ser-232, Ser-293 and Ser-300, is required
CC for reactivation (By similarity). {ECO:0000250}.
CC -!- PTM: Acetylation alters the phosphorylation pattern. Deacetylated by
CC SIRT3 (By similarity). {ECO:0000250}.
