Description

DLST Antibody recognizes dihydrolipoamide succinyltransferase, a mitochondrial enzyme encoded by the DLST gene. Also known as dihydrolipoamide S-succinyltransferase and the E2 component of the 2-oxoglutarate dehydrogenase complex, DLST plays an essential role in the tricarboxylic acid (TCA) cycle. The enzyme participates in the oxidative decarboxylation of alpha-ketoglutarate to succinyl-CoA, a reaction that generates NADH for mitochondrial oxidative phosphorylation. Through this activity, DLST contributes to cellular energy production, carbon metabolism, and the regulation of mitochondrial function.

The human DLST gene is located on chromosome 14q24.3 and encodes a precursor protein of approximately 453 amino acids with a calculated molecular weight near 49 kDa. DLST contains an N-terminal mitochondrial targeting sequence that directs the protein into the mitochondrial matrix, where the targeting sequence is removed during maturation. The enzyme also contains a lipoyl-binding domain, a peripheral subunit-binding region, and a catalytic domain responsible for succinyl transfer. Covalent attachment of lipoic acid to a conserved lysine residue enables the transfer of reaction intermediates between catalytic sites within the multienzyme complex.

DLST functions as the E2 component of the alpha-ketoglutarate dehydrogenase complex, which also contains the E1 enzyme OGDH and the E3 enzyme DLD. These components cooperate to convert alpha-ketoglutarate into succinyl-CoA while reducing NAD+ to NADH and releasing carbon dioxide. DLST forms the structural core of the complex and facilitates the movement of reaction intermediates between its enzymatic components. This organization supports efficient substrate processing and helps coordinate mitochondrial metabolic activity. The Dihydrolipoamide Succinyltransferase Antibody is relevant to research investigating mitochondrial enzyme complexes, TCA cycle regulation, and cellular bioenergetics.

Changes in DLST activity can influence mitochondrial respiration, cellular redox balance, and metabolic adaptation. Impaired alpha-ketoglutarate dehydrogenase complex function has been investigated in neurodegenerative disorders, oxidative stress, and metabolic dysfunction. DLST is also relevant to cancer metabolism, where altered TCA cycle activity can affect the availability of metabolic intermediates required for biosynthesis and cellular proliferation. These associations highlight the importance of mitochondrial enzyme regulation in maintaining cellular homeostasis.

Research involving DLST focuses on mitochondrial energy production, enzyme complex assembly, lipoic acid-dependent catalysis, and metabolic regulation. Understanding DLST function provides insight into how cells coordinate nutrient oxidation with ATP generation and biosynthetic demands. NSJ Bioreagents offers antibodies targeting DLST for studies of mitochondrial metabolism and cellular respiration. A DLST Antibody provides a research tool for examining dihydrolipoamide succinyltransferase expression and its involvement in the TCA cycle, mitochondrial function, and cellular energy homeostasis.
