products description :
DLD (Dihydrolipoamide dehydrogenase), also known as GCSL (glycine cleavage system L protein), is a component of the glycine cleavage system as well as of the alpha ketoacid dehydrogenase complexes. DLD is a flavin-dependent oxidoreductase and functions as a component of the alpha-keto acid dehydrogenase, the pyruvate dehydrogenase, the alpha-ketoglutarate dehydrogenase, the branched-chain alpha-keto acid dehydrogenase and as the L protein in the mitochondrial glycine cleavage system. Mutations in DLD protein can result in MSuD (maple syrup urine disease) and congenital infantile lactic acidosis. Recombinant human DLD protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

ncbi summary :
This gene encodes a member of the class-I pyridine nucleotide-disulfide oxidoreductase family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. In homodimeric form, the encoded protein functions as a dehydrogenase and is found in several multi-enzyme complexes that regulate energy metabolism. However, as a monomer, this protein can function as a protease. Mutations in this gene have been identified in patients with E3-deficient maple syrup urine disease and lipoamide dehydrogenase deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
uniprot summary :
DLD: a multi-functional mitochondrial enzyme. An enzymatic component of the mitochondrial glycine cleavage system, the pyruvate dehydrogenase complex (PDHC), the alpha-ketoglutarate dehydrogenase complex, and the branched-chain alpha-keto acide dehydrogenase complex. Is the E3 component of the PDHC that catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2. The E3 component has dihydrolipoamide dehydrogenase activity. The PDHC contains 20-30 copies of pyruvate decarboxylase tetramers (2 alpha:2 beta)(E1), 60 copies of dihydrolipoamide acetyltransferase (E2), six homodimers of dihydrolipoamide dehydrogenase (E3), plus E3 binding proteins. Defects in DLD are a cause of maple syrup urine disease (MSUD), characterized by mental and physical retardation, feeding problems and a maple syrup odor to the urine. The keto acids of the branched-chain amino acids are present in the urine, resulting from a block in oxidative decarboxylation. Differentially expressed in the Wernicke s Area from patients with schizophrenia. Inhibited by 5-methoxyindole-2-carboxylic acid (MICA). Protein type: EC 1.8.1.4; Mitochondrial; Oxidoreductase; Carbohydrate Metabolism - pyruvate; Carbohydrate Metabolism - glycolysis and gluconeogenesis; Amino Acid Metabolism - glycine, serine and threonine; Carbohydrate Metabolism - citrate (TCA) cycle; Amino Acid Metabolism - valine, leucine and isoleucine degradation.

Molecular Function: mercury (II) reductase activity; FAD binding; mercury ion binding; dihydrolipoyl dehydrogenase activity; NADP binding.
