Comment typeDescription
Catalytic ActivityPyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO(2).
CofactorName=thiamine diphosphate; Xref=ChEBI:CHEBI:58937; Evidence={ECO:0000250};
FunctionThe pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3) (By similarity). {ECO:0000250}.
Subcellular LocationPlastid, chloroplast {ECO:0000305}.
SubunitTetramer of 2 alpha and 2 beta subunits. {ECO:0000250}.
