Pyruvate dehydrogenase (PDH) deficiency is a congenital degenerative metabolic disease resulting from a mutation of the pyruvate dehydrogenase complex (PDC) located on the X chromosome. While defects have been identified in all 3 enzymes of the complex, the E1-α subunit is predominantly the culprit.
PDH may refer to: Angiotensin-converting enzyme, an enzyme; Plesiochronous digital hierarchy, in telecommunications networks; Pound–Drever–Hall technique for stabilizing a laser's output; Pyranose dehydrogenase (acceptor), an enzyme; Pyruvate dehydrogenase, an enzyme
The PDHB gene is responsible for the coding of the E1 beta subunit of the pyruvate dehydrogenase complex. The DLAT gene is responsible for the coding of the E2 subunit, and the PDP1 is responsible for producing the PDH phosphatase catalytic subunit that catalyzes PDH dephosphorylation. This dephosphorylation activates the complex.
Pymol-generated image of E1 subunit of pyruvate dehydrogenase complex in E. Coli. The E1 subunit, called the pyruvate dehydrogenase subunit, is either a homodimer (comprising two “α” chains, e.g. in Escherichia coli) or a heterotetramer of two different chains (two “α” and two “β” chains).
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.

Pyruvate dehydrogenase (EC 1.2.4.1) is responsible for the oxidation of pyruvate, dihydrolipoyl transacetylase (this enzyme; EC 2.3.1.12) transfers the acetyl group to coenzyme A (CoA), and dihydrolipoyl dehydrogenase (EC 1.8.1.4) regenerates the lipoamide. Because dihydrolipoyl transacetylase is the second of the three enzyme components ...
