Dihydrolipoamide Dehydrogenase/DLD Products

Dihydrolipoamide dehydrogenase (DLD), also known as LADH, is an NAD-dependent oxidoreductase in the mitochondrial matrix. DLD serves as the E3 subunit of four mitochondrial enzyme complexes: pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, branched chain alpha-ketotacid dehydrogenase, and the glycine cleavage system. The involvement of DLD in the regulation of lipid peroxidation and lactate metabolism is important for mouse hippocampal neuroblast proliferation and hamster sperm capacitation, respectively. DLD polymorphisms in insects can increase their resistance to the pesticide phosphine gas, while they can increase the sensitivity to arsenite in the nematode C. elegans.
