MeSH definition : A multienzyme complex responsible for the formation of ACETYL COENZYME A from pyruvate.
The enzyme components are PYRUVATE DEHYDROGENASE (LIPOAMIDE); dihydrolipoamide acetyltransferase;
and LIPOAMIDE DEHYDROGENASE. Pyruvate dehydrogenase complex is subject to three types
of control: inhibited by acetyl-CoA and NADH; influenced by the energy state of the
cell; and inhibited when a specific serine residue in the pyruvate decarboxylase is
phosphorylated by ATP. PYRUVATE DEHYDROGENASE (LIPOAMIDE)-PHOSPHATASE catalyzes reactivation
of the complex. (From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd
