CC   -!- FUNCTION: The pyruvate dehydrogenase complex catalyzes the overall
CC       conversion of pyruvate to acetyl-CoA and CO(2). It contains
CC       multiple copies of three enzymatic components: pyruvate
CC       dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and
CC       lipoamide dehydrogenase (E3) (By similarity).
CC   -!- CATALYTIC ACTIVITY: Pyruvate + [dihydrolipoyllysine-residue
CC       acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue
CC       acetyltransferase] S-acetyldihydrolipoyllysine + CO(2).
CC   -!- COFACTOR: Thiamine pyrophosphate.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain (By similarity).
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
