CC -!- FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall
CC conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple
CC copies of three enzymatic components: pyruvate dehydrogenase (E1),
CC dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase
CC (E3).
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 -!- ACTIVITY REGULATION: E1 activity is regulated by phosphorylation
CC (inactivation) and dephosphorylation (activation) of the alpha subunit.
CC {ECO:0000250}.
CC -!- SUBUNIT: Tetramer of 2 alpha and 2 beta subunits. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000269|PubMed:14671022}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, rosettes and flowers.
CC {ECO:0000269|PubMed:7590338}.
CC -!- INDUCTION: Induced by cadmium. {ECO:0000269|PubMed:16502469}.
