Summary
Enables dihydrolipoyl dehydrogenase (NADH) activity; glycine dehydrogenase (decarboxylating) activity; and oxidoreductase activity, acting on the aldehyde or oxo group of donors. Involved in several processes, including 2-oxoglutarate metabolic process; alpha-amino acid metabolic process; and hydrogen peroxide metabolic process. Located in mitochondrial nucleoid. Part of glycine cleavage complex; oxoglutarate dehydrogenase complex; and pyruvate dehydrogenase complex. Used to study disease of metabolism. Human ortholog(s) of this gene implicated in maple syrup urine disease. Orthologous to human DLD (dihydrolipoamide dehydrogenase). [provided by Alliance of Genome Resources, Apr 2025]

  • Dihydrolipoamide dehydrogenase; the lipoamide dehydrogenase component (E3) of the pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase multi-enzyme complexes; PDH complex is concentrated in spots within the mitochondrial matrix, often near the ERMES complex and near peroxisomes; LPD1 has a paralog, IRC15, that arose from the whole genome duplication
