DLD encodes dihydrolipoamide dehydrogenase (E3), a flavin-dependent oxidoreductase that reoxidizes dihydrolipoamide to lipoamide while reducing NAD+ to NADH. As a shared E3 subunit, DLD supports mitochondrial energy metabolism through the pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, and branched-chain α-ketoacid dehydrogenase complexes, linking glycolysis and amino acid catabolism to the TCA cycle and oxidative phosphorylation. Disruption of DLD perturbs redox homeostasis and mitochondrial function, altering NADH/NAD+ balance and reactive oxygen species handling. Genetic variation in DLD is associated with inborn errors of metabolism characterized by impaired oxidative metabolism and lactic acidemia, and dysregulated mitochondrial energetics is relevant to neurodegeneration and cancer bioenergetics research.
DLD Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DLD locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DLD. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt DLD function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of DLD-disrupted clones.
