  2. Pyruvate dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase

    Pyruvate dehydrogenase is an enzyme that catalyzes the reaction of pyruvate and a lipoamide to give the acetylated dihydrolipoamide and carbon dioxide. The conversion requires the coenzyme thiamine pyrophosphate .

  3. Pyruvate dehydrogenase complex - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_complex

    Pyruvate dehydrogenase complex. Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. [1] Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric ...

  4. Pyruvate dehydrogenase (lipoamide) beta - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_(l...

    The PDH genes that comprise the E1 subunit are 1.36 kilobases long (alpha) and 1.69 kb long (beta). [7] The PDHB gene has a total of 10 exons and 9 introns. All intron-exon splice junctions follow the standard GT/AG rule. There was an Alu family found in introns 2 and 8.

  5. Dihydrolipoyl transacetylase - Wikipedia

    en.wikipedia.org/wiki/Dihydrolipoyl_transacetylase

    Pyruvate decarboxylation requires a few cofactors in addition to the enzymes that make up the complex. The first is thiamine pyrophosphate (TPP), which is used by pyruvate dehydrogenase to oxidize pyruvate and to form a hydroxyethyl-TPP intermediate. This intermediate is taken up by dihydrolipoyl transacetylase and reacted with a second ...

  6. Pyruvate dehydrogenase (lipoamide) alpha 1 - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_(l...

    Pyruvate dehydrogenase E1 component subunit alpha, somatic form, mitochondrial is an enzyme that in humans is encoded by the PDHA1 gene.The pyruvate dehydrogenase complex is a nuclear-encoded mitochondrial matrix multienzyme complex that provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle by catalyzing the irreversible conversion of pyruvate into acetyl-CoA.

  7. Formate C-acetyltransferase - Wikipedia

    en.wikipedia.org/wiki/Formate_C-acetyltransferase

    In enzymology, formate C-acetyltransferase (pyruvate formate lyase) (EC 2.3.1.54) is an enzyme. Pyruvate formate lyase is found in Escherichia coli [1] and other organisms. It helps regulate anaerobic glucose metabolism. Using radical non-redox chemistry, it catalyzes the reversible conversion of pyruvate and coenzyme-A into formate and acetyl ...

  8. Pyruvate dehydrogenase kinase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_kinase

    The opposite action of PDK, namely the dephosphorylation and activation of pyruvate dehydrogenase, is catalyzed by a phosphoprotein phosphatase called pyruvate dehydrogenase phosphatase. (Pyruvate dehydrogenase kinase should not be confused with Phosphoinositide-dependent kinase-1, which is also sometimes known as "PDK1".)

  9. Pyruvate decarboxylation - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_decarboxylation

    Pyruvate dehydrogenase complex reaction. Pyruvate decarboxylation or pyruvate oxidation, also known as the link reaction (or oxidative decarboxylation of pyruvate [1]), is the conversion of pyruvate into acetyl-CoA by the enzyme complex pyruvate dehydrogenase complex. [2] [3] The reaction may be simplified as:
